Video Transcript for Review of JR Products Wiring Parts - Single Rocker Switch - 37212595

Hey everyone. I'm Ellen here at and we're going to be taking a quick look at the single rocker switch. This allows you to flip the on and off switch for your lights. Maybe a small electrical appliance in your vehicle, fan or something like that. It's just a really easy way to replace that switch if it happened to go bad or maybe add one in if you're adding in some kind of accessory lighting such as other things in your RV or really anywhere that you'd want it to go.So let's take a little closer look at our switch. It is labeled on and off to make it easy.

Have two prongs back there to connect our wires into. This is going to be a single pole single switch. So just has one on and off connection to make.It works at 16 amps at 125 volts or 12 amps at 250 volts AC. It can also power a three quarter horsepower at 125 volts up to 250 volts AC or 10 amps at 14 volts DC. So whether this is for AC or DC power, it can still work.As far as the size, overall it's about 3/4 of 1" by about 1 1/4" and the overall depth including the switch.

It's about 1 1/4". The cutout is about 1 1/8" tall if you allow for a little bit of give on those prongs. That's what's going to snap in between the cutout to hold it in place as the tension on those two tabs. So the smallest that it could go is 1" but it would be really tight on those. So about 1 1/4" or an 1 1/8" between there should work just fine.Then width-wise, it's about 1/2".

It's black in color made in the USA and that's about all there is to it for our single rocker switch. Hope this video has been helpful in deciding if this is the right one for you. We do have some other options available here at So check those out and thanks for watching..

Perfect part. Exactly what I ordered and works great.


I had a few stuck switches that I needed to change for the customer. Switches installed very easy.


Description of the part was perfect so I knew exactly what I was ordering. Shipping was prompt and delivery as expected. Excellent service! A vendor I’ll trust to return to for any RV needs.


2nd time of making a purchase, delivery was timely and and I love the short installation video that comes with them.

  • What Size Terminal Connectors Are Used on the Single Rocker Switch 37212595
    The width of the prongs that you would connect the wires to on the Rocker Switch # 37212595 are 1/4" wide, so you'd need 1/4" terminal connectors.

  • Is There an Available Exterior 110v/120v Light for 1996 Rockwood 2307 Pop Up Camper
    I have a solution for you, but the Optronics LED RV Exterior Scene Light # UCL41CB is designed to work on 12v power only, so it's not going to work on a 110v/120v feed. Unfortunately all of the lights we've got for this application are going to be 12v lights. With that said, if you have a battery on your camper, you could run the wiring for the # UCL41CB to the battery and power the # UCL41CB that way, so you'd have a 12v power source. You would want to install a switch like the Single...

  • Replacement 12 Volt On Off Rocker Switch
    Yes we do have them. I personally prefer the Universal-Design Rocker Switch - SPST - On-Off - 12 Volt - 20 Amp - 3-Blade - Red Pilot Light # PK34360. The red indicator light lets you know if it is on or off from a distance. If you like the simple standard look we have the Single Rocker Switch - Labeled On/Off - SPST - Black # 37212595. It doesn't have a light indicator it is just labeled with ON/OFF. We also have the Single Rocker Switch - 12V - On/Off - SPST - Black Plate with Blue Illuminated...

  • On/Off Switch for a KiB Services Panel
    The Ventline # BL0108-00 switch you referred to is very similar but fits a cut out hole measuring 3/4" X 1/2" instead of the 1" X 1/2" sizing that you want. The closest items we carry are, JR Products # 37212595 uses 1-1/8" X 1/2" cut out (very close) JR Products # 37213405 uses 1.125" X 0.55" cut out (not as close)

  • Will Back Up Sensors on 2016 Toyota Sienna Need to Be Disabled When Towing
    Actually, you really shouldn't need to do anything with the sensors because they'll only activate when the vehicle is in reverse. If you find that having them sound while your backing is annoying, you can install a switch such as # 37212595 inline with the power circuit feeding the sensors so you can turn them on and off as needed. You'll need to trace the sensor wires from the bumper, and locate which wire in their harness carries power. Install the leads for the switch inline on that...

  • Parts Needed to Install Westin Off Road Lights
    Thanks for your purchase of the Westin Sportsman Grille Guard # 40-3825 for your 2017 Toyota 4Runner! In order to install the MaxxTow Off-Road Lights # MT80637-2 on the grill guard you need a power source, wiring, a switch, and some connectors. For the power source I do recommend using the Firestone Fuse Circuit Tap Kit # F2526 because it will help to protect your wiring. If you don't go this route then you'll have to place a fuse or circuit breaker on a power wire that's hooked up to...
