Video Transcript for JR Products Single On/Off Rocker Switch Review and Installation

Hi there RV and camper owners, today we're going to be taking a look at JR Products on-off rocker switch. These are available in either black, white, or brown to match your interior. And you can see how smooth that switch is there. It's a nice large switch, so it's very easy to identify, and for a light switch I really like it, because it has such a large switch, when it's dark outside and you're trying to fumble through the hallways, you can easily identify this switch without having to see it, and you can clearly feel what position it's in, since the way the switch kind of sticks out here. And since this is a simple on-off switch, it's great for all of your 12 volt accessories. Some other examples besides just lights might be a range vent above your oven.

Exterior lights are another good example. Maybe a roof vent, pretty much anything that you just, you want it to be on certain times and off often other times, maybe it's for a pump for your water system to help you clean that out. There's a lot of different applications. It's just whenever you want to turn it on, you simply hit the switch, and when you're gonna turn it off, you hit it once again. The switch is an easy replacement since it has a nice bezel that covers up all the mounting hardware on there.

It helps you get a nice, quick, clean installation, because you don't have to be too particular about the stuff underneath. If you follow along with us, we'll show you how to get a switch replaced. We've recently serviced this motor home for our customer and they mentioned to us that their lights weren't working properly. We came in here and we turn the switch on and off, nothing's happening, we did verify that other accessories work, just not this one here. So that means it's probably an issue with the switch, the lights, or the wiring.

Well, since both lights don't work, more often than not that means it's probably not the lights, it's probably the common part that controls both. So I highly suspect that our switch must be open internally, it's not closing the contacts. So we're going to go ahead and pop it off of there, inspect our switch, and then get us a new one installed if it ends up being damaged. To remove the switch you'll simply take a flat-bladed screwdriver, and I just gotta put a little bit of side pressure on it, and then you can get this underneath there, and you can pop the cover off here. So, there we go.

And that just pops off of there. That'll reveal two screws that hold our switch in place. You can use either a number two square drive, or a phillips bit to remove these. Now your switch at home may look slightly different than this if you're replacing a factory switch, but as long as it's the same relative size, this replacement switch we're going to be putting on should work just fine. So now we can just pull our switch down, looks like our wires aren't very long, so you don't want to pull too hard. We'll just get those disconnected from there. Make sure that they don't fall back up into place. So we're just going to kind of put some, a little bit of pressure on those, tucking them sideways so that they don't fall up in there on us. And with this switch they can't be easier to replace it, because if you look here it's just got two prongs on the back. This switch is either on or off. So since this is just a switch that's either letting current pass through it or not, it doesn't matter how we wire it up to the switch. You can put either the hot or the cold on here, and it's still, on either prong, and it's still going to complete the circuit and send it onto our lights. So we can just take this old, no good switch here, and we're going to grab our new one, and we're just going to simply plug it in. So now we've got our new switch from JR Products. It's a similar shape, size, and style. We're using one that's black so it matched the old one, but these do also come in white if you would prefer that to match your particular interior. So now we'll just take these two leads that we removed from our old switch. We're just going to slide these onto the prongs. So the same size, and we can already see there when we touched it, we had our switch in the on position, the light flickered on. So we know that our new switch is working properly. I went ahead and turned it off, just so it's not blinding me while I'm trying to get these plugged in. Wanna make sure you get them all the way plugged in. We don't want to have exposed leads up in there. All right, and once you've got them inserted, we can put our switch up into place. And then we're just going to reuse the hardware that we took out of there. Now, if you're adding your own switch, you will have to provide your own hardware, and you'll have to trim out your hole. The nice thing about this though is the switch does come with a bezel here. So that way you can ensure that your hardware is not going to be seen. And when you go to cut out your hole, you can cover up any nasty marks you made while cutting. And it also makes a great template for determining the size hole you're going to need to cut out. If you could just sit this up here, maybe put it the other way like this, trace out that hole, cut that out, and that way, you know your switch is gonna push right up in there. And if you look where the screws are here, you can be sure that this hole here is not going to cut out too much, so you're still gonna have plenty of meat for your screws to go into. The cover's just got a couple of little tabs you can see here in opposite corners, those line up with the prongs there, and it just snaps right into place. So now we can test it out, and our switch is now working properly again. We've got lights over here, so you can see this is a nice, quick, easy replacement that you can easily do at home in a matter of minutes. And all you really need is a screwdriver..

Thank you! Just what I ordered. We did not like the light switch in our RV garage so purchased this to replace it! Worked perfectly!


Fast shipping part was exactly what we needed couldn’t ask for better service


Just what is needed


Perfect fit to replace broken switch in my enclosed cargo trailer. In fact, it appears to be identical.


Works well


Easy ordering process and fast shipment, large inventory.


I used the rocker switches in my Tea House that has a 12 volt solar system. All of the switches are working perfectly. Good design.

  • Does The Pollak Light Duty Toggle Switch Come With A Cover Plate
    The Pollak Light-Duty Toggle Switch # PK34513 does not come with a cover. It has a small screw on nut and on/off tag that would sit outside of the hole to keep the toggle lever in place. I've installed this switch a ton of times in different trailers and I typically just drill a small enough hole to only have the lever stick through. In the video I've attached below I wasn't able to get behind the wall to hide the body of the switch so I used a small metal plate we had laying around to...

  • Wiring Instructions for QH16CTS Optronics Halogen Utility Lamp
    Due to the multitude of installation possibilities, Optronics doesn't provide installation instructions for their # QH16CTS Halogen Utility Light. This being said, I'd be happy to explain the electrical connections for you. The red power wire would attach to a 12-volt power source, and the lamp picks up its ground connection via it's attachment to metal that's in contact with the vehicle frame. If the lamp is mounted to a non metal surface, a ground jumper would need to be ran from the...

  • Availability of SPDT Switch that Has Bezel
    The closest SPDT switch we offer to the # 37212225 that has a bezel around it would be the part # 37212675 which is an on/off/on switch. For a similar on/on you'd want the part # 37212625. If you need the switching to be momentary we have the part # 37213845 which is on/off/on. We do not offer just the bezel of the switch you mentioned.

  • How Can I Turn My Furrion Camera System To A Security System?
    You should be just fine using just one 12V PWM Filter for RV Backup Camera Systems # VGR64VR with your current Furrion system. To be able to use your Furrion system as a security monitoring system, you will need to wire your cameras to your RV's battery instead of the running lights or reverse lights. From here, you can add a rocker switch # 37212225 that way you can turn the system on whenever you wanted to. Attached is a review and installation video of # 37212225 for you to check...

  • Installing Optronics OPT58FR Opti-Brite LED Dome Light
    I'd be happy to help you with that. The black wire of the # OPT58FR is the power supply, and the white is ground. You can certainly wire the lamps together so they'll operate on a rocker switch such as # 37212225. You can run each ground individually, or connect them all together and ground them to the trailer frame. You'll want to install the switch inline on the power leg from the 12-V power source. I've linked to a product description video for the dome light and the switch.

  • Recommended Fan-Tastic RV Roof Vent For Use With A Wall Switch
    Technically any vent can run of a wall switch if you wire it that way so you'd be able to use the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote # FV807350 and just run the wires for it to a switch like the Single Rocker Switch # 37212225. If you already have a switch nearby that you just want to add an additional switch onto you can use the Double Rocker Switch # 37212235. I've attached a video below where I'll walk you through the installation of this switch.

  • Wall Light Will Not Turn Off - Test Wall Switch
    Your Gustafson # 277-000446 is likely okay, but your wall switch has an issue it seems. Useing the Performance Tools # PT89ZR multimeter, or similar, test the voltage before and after the wall switch, with the switch in off and on positions, to determine if the wall switch is working properly. If you are able to turn the 12 volts off using the wall switch, but the light stays on, then there is no way that this is the switch for this light as there will be no power for the light to work...

  • How To Install Furrion Vision S Camera System So It Works When Trailer Is Unhooked From Truck
    Yes, you would need to wire the cameras of the Furrion Vision S Wireless RV Observation Camera System w/ Side Marker Light Cameras - 7" Screen # FCE48TASL-07 differently to use them when you are not hooked up to your truck, or you would need to find a way to send power to only the running light circuit from your trailer's battery when you are hooked up to shore power. How we typically recommend you do this is running a power wire to each camera yourself and then connecting them to a switch...

  • How To Prevent iRV RV Stereo From Draining Battery
    I am not able to identify a way of turning off the backlighting for your iRV RV Stereo, # IRV64FR. I suggest you review your owners manual or install an on/off switch such as the 12V Single Rocker Switch, # 37213885 or the Single Rocker Switch - On/Off, # 37212225 for black and # 37213575 for white. Doing so will isolate the iRV RV Stereo, # IRV64FR preventing it from draining your battery.

  • Wiring A Furrion Camera System To Work While Not Hooked Up To The Tow Vehicle
    Your trailer is only going to have power running to the running light and reverse light circuits (one of which is powering your camera) while hooked up to the truck. To bypass this you can wire the lights to the battery using two diodes # RM-792 (to prevent feedback), an in-line fuse # 55151, a switch # 37212225 to control the power running to the camera as needed, and some wiring. You'll want to splice the power wire from this switch together with the power wire already running to your...

  • Recommended Light Switch For An LED Trailer Dome Light
    The LED Trailer Dome Light for Remote Switch # 3375625336 doesn't come with a remote but can be easily wired to a switch for activation. The switch you use is really just going to depend on what you like aesthetically or simply have space for. In an enclosed trailer with open walls I would use a switch like the Pollak Light-Duty Toggle Switch # PK34513 since it has a small footprint and the back is covered so you won't have to worry about the switch grounding out to the metal walls of...

  • Does Optrionics RV Dome Light ILL36CB Have Built In Light Switch?
    The Optronics Opti-Brite LED RV Dome Light # ILL36CB you were looking at does not include a light switch, so to operate this light you will need to add one like the # 37212225. An easier option is the # 328-001-902XPW which has a switch built in to the light. I included a video of the # 328-001-902XPW for you to take a look at.

  • Parts Needed To Provide Power To LED Courtesy Light for RVs # 328-002-04W
    The LED Courtesy Light for RVs # 328-002-04W only require a very small 12 volt power source since each light only uses 0.02 amps of power. If you have any 12 volt lighting or fans you will be able to tap into their power and add a Switch # 37213405 or # 37212225 allowing you to switch the lights on and off when needed. If you do not have a 12 volt power source near you will need a Power Converter # FV1101-09 to adapt from 110 volt power to 12 volt power. Then you will need the male end...

  • 12 Volt Power Port Needed in RV to Power Furrion Vision S Wireless RV Observation Camera System
    The Furrion Vision S Wireless RV Observation Camera System w/ Side Marker Light Cameras, # FCE48TASL-07 is a 12VDC system. If you have a 12VDC power port in the RV simply use the same Furrion Monitor Power Cable, # C-FOS07TAPK-006. If you do not have a 12V power port, you can install one with the 12V Power Outlet for RVs, # 37215105 and the Mounting Plate for 12V Socket or USB Outlet, # 37215155. Or, you can buy another Furrion Monitor Power Cable, # C-FOS07TAPK-006 and cut off the adapter...
