great switch



by:

Wires are a little short but that's what butt connectors are for.



by:

Switch mounded up ok. I fabricated a shield to cover the switch so that it would not be jerked around and possibly fail due to wiggling around.

  • Re Inserting Pin into Breakaway Switch
    The piece of the switch that pulled out is keyed, so that it can only be inserted back into the switch one way. Try rotating the piece, eventually you will find the position in which it will go in. You will also want to make sure that the pin was not damaged.

  • What are the Functions of the 3 Wires on Hopkins LED Breakaway Switch, # HM20059
    You are correct, the Hopkins LED Breakaway Switch, # HM20059, does have 3 wires. The white wire is the ground wire and should be attached to the trailer frame. The blue wire on the switch will connect to the electric brake wire coming from the trailer side connector. The black wire goes to the break away battery. This part is just a switch, if you need a new system, I recommend Engager Trailer BreakAway Kit with Charger and Tester, # 20099. I have included a link to the installation details...

  • Wiring 3-Wire Breakaway Switch as Replacement for 2-Wire Switch
    You can absolutely wire up a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires # HM20059 to replace your 2-wire switch; the difference is that the 3-wire switch has a dedicated ground wire while the 2-wire switch grounds through its mounting hardware. The Hopkins LED Breakaway Switch # HM20059 has the white ground wire, a blue wire which will splice into the brake wire coming out of your trailer connector and a black wire which will connect to the breakaway box.

  • Where Does 3rd Wire On 3-Wire Breakaway Switch Get Connected To?
    The 3rd wire on a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires # HM20059 gets grounded to the trailer frame or tied in to the main ground on your trailers tongue. The only difference between a 2-wire and 3-wire switch is the 3-wire switch has its own ground wire. I included a wiring diagram of the # HM20059 for you to take a look at.

  • Can Trailer Breakaway Pin be Easily Substituted If Broken On Trip
    Breakaway plungers are pretty unique so you won't be able to easily substitute something to get you back on the road. I could tell you to cut the wire on the switch so that the brakes would release so that you could get home to order a new switch like with the part # HM20059, but since that's not safe I really can't recommend that as an ideal solution...

  • Recommended Breakaway Switch Kit For Trailer and How Does It Get Wired?
    For a breakaway switch I recommend going with the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # 20400 as it includes the battery with a built in battery charger and tester needed. To wire the # 20400 you will make the following connections: Black wire from the battery to the 12v power wire from your 7-way connector White wire from the battery to the ground wire on your 7-way connector Blue wire from breakaway switch to brake output wire...

  • LED Status on Hopkins LED Breakaway Switch
    For your Hopkins LED Breakaway Switch part # HM20059 the led indicator should only be lit when the breakaway pin is pulled, and should be solid. When the pin is inserted and the trailer hooked up it should not be on at all. If you do not have the breakaway system wired correctly, the brakes may not be getting the signal from the breakaway box. It sounds like there may be a wiring issue with the breakaway switch. I recommend that you check all your connections, specifically check the white/ground...

  • Should Trailer Breakaway Switch to Very Difficult to Pull
    Glad everything worked out okay but sorry to hear about your breakaway pin not doing the ONE JOB it was designed for. I would go with an all new switch just to be careful and because they are relatively inexpensive. I would go with the Hopkins part # HM20059 which we know works well and wouldn't have same issue you had. Just make sure the pin would pull straight from the switch if the trailer was to become disconnected again and you'd be fine. The force to pull the pin shouldn't be too...

  • Do You Have a Replacement Pin and Lanyard for a Trailer Breakaway Switch
    If you have the Tekonsha trailer breakaway kit you will need the Replacement Tekonsha Trailer breakaway Switch, part number 420000, to replace your lost or broken cable and pin. If you have a Hopkins Breakaway system then you can order the Replacement Cable and Pin for Hopkins Breakaway Switches, part number HM20051 which works on the HM20059 and HM20060 breakaway switches.

  • How To Wire Hopkins LED Breakaway Switch Part HM20059
    In regards to the Hopkins LED Breakaway Switch part # HM20059; the white wire is ground, the black wire is for 12 volt power, and the blue wire is for electric brake output. If you have a two wire switch, the above will work but the Hopkins Replacement Break-Away Switch part # HM20010 would be better since there are less connections but you can use either. The Replacement Break-Away Switch grounds though the mounting hardware which is why an additional ground is not needed.

  • Trouble Re-Installing Breakaway Pin Back In Switch
    The majority of breakaway pins are keyed which means they can only be inserted back into the switch one way like the Hopkins LED Breakaway Switch part # HM20059 for example. Therefore, most likely you just don't have the pin in the correct position. That said, if the pin is damaged or there is foreign objects inside the switch that could cause issues as well. Please note, it does take a fair amount of force to remove and reinstall the pin back inside the switch. That said, there isn't...

  • How to Wire Hopkins Breakaway Switch # HM20059 with Hydrastar Electric Over Hydraulic Brake Actuator
    The yellow wire from the Hydrastar # HBA16 will connect to the blue wire of the Breakaway Switch # HM20059. The blue wire from the Breakaway Box # HM20121 connects to the black wire from the switch. The white wire from the switch is strictly a ground for the LED light and should connect directly to the trailer's frame.

  • Replacement Breakaway Kit Switch Recommendation for RV Breakaway System
    Put the pin back in and check the wiring of the switch to make sure nothing was damaged. Nothing should be reset but the switch could have been damaged or the wiring as well. For a replacement switch though we have the Hopkins kit part # HM20059 which would work well as a replacement.

  • No Brakes On Trailer When Pin Is Pulled On Breakaway Switch
    I have attached a couple of helpful articles that explain how to install and test breakaway systems. I spoke with my contact at Hopkins and they told me that the light should not illuminate unless the cable has been pulled. Since you said the light is blinking when hooked up, it sounds like there may be a problem in the wiring. You can also test the battery to make certain it has a full charge. If you do not have the breakaway system wired correctly, the brakes may not be getting the signal...

  • Can a 3-Wire Breakaway Switch Be Substituted for a 2-Wire Breakaway Switch
    Yes, you can use a 3-wire breakaway switch like part # HM20059 in place of a 2-wire breakaway switch like part # HM20010. The connections will be the same and the only differences is that the 2-wire switch grounds through the mounting hardware whereas the 3-wire switch grounds with a single wire. The blue wire on the switch will connect to the electric brake wire coming from the trailer side connector. The black wire goes to the breakaway battery. If it turns out it is not the switch...

  • How to Turn Off LED Indicator on Hopkins LED Breakaway Switch
    In order to turn off/deactivate the LED indicator light on the Hopkins LED Breakaway Switch # HM20059 referenced in your question, you simply will not connect the white ground wire on the unit. If the white wire is not grounded, the LED indicator will not function but everything else will work like normal. For a non-LED version, you can also use the Hopkins Replacement Break-Away Switch # HM20010.

  • Replacement Breakaway Pin for Landa ECOS Trailer
    If you can provide me with the brand and model of the breakaway system that is used on your Landa ECOS Trailer then I can go about seeing if we have a replacement breakaway pin for you. However, the breakaway pins are not all universal. Unfortunately, I don't have any information as to what the brand and model is for your trailer. Therefore, the only option we can currently offer you is a new switch and pin for the Trailer Breakaway Kit part # 3802348 for two wire systems or the Hopkins...
