• What Does a Trailer Breakaway Kit Do
  
• Yes, what you described is the correct purpose of a trailer breakaway braking system. If for some reason the hitch and the safety chains were to fail and the trailer was to be completely unattached from the tow vehicle the breakaway kit would activate the trailer brakes so that it would stop as soon as possible. You would want to ensure that the length of the cable is enough so that under normal situations the pin would not get pulled while the trailer is still safely connected to the...

• 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.

• Replacement Pin for an LBS48-16 ESCO Break Away Switch
  
• While we do have numerous replacement break away system pins, all of which are similar, I cannot guarantee that any will fit your ESCO brand switch because they have not all been tested together. The difference in cost between a replacement pin and a new switch is minimal so I advise just replacing the switch with # HM20010.

• Replacing Breakaway Switch On a Trailer with ESCO Breakaway System
  
• You likely can use any replacement switch since all they do is complete a circuit when the pin is pulled out. One wire on the switch should be connected to the positive battery terminal on the trailer. The other will tee into the wiring leading from the trailer connector to the brake magnets like in the diagram I have included. Just follow the wires on the old switch to where they are connected and remove them. I have also included a link to the right that should help.

• Wiring a Trailer Breakaway Kit on a Bigfoot Travel Trailer
  
• In order for a break away system to power electric trailer brakes, it will need a 12 volt power source (a battery mounted on the trailer). The battery has to provide a full 15 minutes of braking power to comply with DOT regulations. On the trailer connector there is a wire that goes back to the trailer brakes. This wire may be black or blue depending on the specific system. Attach one wire from the switch to the wire that goes to the trailer brakes. There should be another wire, usually...

• Solution for Lost Plunger for Esco Model 2010 Breakaway Switch
  
• The easiest solution I can provide is to just replace the entire switch with the part # 420000 that you referenced. Trying to replace just the plunger can be challenging and since all of the switches are basically universal it's just easier to replace the whole thing.

• Identifying a Trailer Breakaway Switch with ESCO Printed on the Switch
  
• ESCO actually stands for Elkhart Supply Corporation, that is the brand of your breakaway switch. Most likely it is part number LBS48-16. If you are looking for a replacement switch the Hopkins Replacement Break-Away Switch # HM20014 should work well for you. I attached a couple FAQ articles on breakaway switches for you to check out as well.

• Troubleshooting Trailer Breakaway Switch and Grounding Wire On 14-Foot EZ-Dump Trailer
  
• After speaking to my contact in the electronics department at Cequent, I have discovered what could be the source of the problem. If the ground is disconnected, the breakaway battery ground is disconnected, and if the trailer is not attached to a tow vehicle, the 12-volt current you are detecting in your trailer frame is the current that should be going to your ground. Try the test again with these issues resolved and the problem should take care of itself. If you continue to have the...

• How Does Replacement Breakaway Switch Wire into Circuit
  
• I don't have a specific way to recommend wiring the part # 420000 to a dump trailer but essentially this switch wires into a circuit by just cutting the wire and splicing it between the two wire ends. Whenever the plug of the switch is inserted the circuit is dead and then when the pin is removed the circuit is active. I attached an install video for you to check out as well.

• Breakaway Switch Diagram for Installation on a Dump Trailer with Trailer Mounted 12 volt Battery
  
• I attached a diagram showing how a breakaway switch, like part # 420000, would be wired to a trailer mounted battery like the one on your Loudo dump trailer. With this type of setup you would not want to pull the breakaway switch with the trailer connected to the vehicle, to avoid a short circuit situation which could damage your brake controller. When testing the breakaway switch just be sure to disconnect the trailer connector from the truck, as it would be in a breakaway situation. The...

• Replacement Breakaway Switch Recommendation for UPG D2901 Solution
  
• I wish we carried that but we do not. One solution we can provide is to replace the entire switch with part # 420000. This will be the easiest solution and will work well as the switches are universal.

• Trailer Breakaway Switch Smoked/Melted When Trailer Was Unattended
  
• The Tekonsha Replacement Trailer Breakaway Switch # 420000 that you referenced should work fine as a replacement part for your trailer's breakaway system. As for the cause for a smoking/melting switch, my first thought is a malfunctioning breakaway battery charger. If this unit failed it might have taken out the switch with it. We offer the Tekonsha Battery Charger for Trailer Breakaway Systems # 1024, whose installation is shown in the linked diagram.

• Troubleshooting Wiring Issue of Trailer Breakaway System
  
• Most likely the problem is not insufficient amperage if the fully charged breakaway battery won't apply the brakes. You can test this however by running a jumper wire from a car battery to see if the much higher amperage of that battery does the job. I would be very surprised if the problem wasn't the wiring. Electric stuff can be frustrating to diagnose, but if you go over all of the connections and compare the setup to the diagram I attached you should be able to find the problem.

• Installation of Curt Triflex Brake Controller and Trailer Breakaway System
  
• When you state you have the harness coming for the Curt product, I assume you are meaning the custom wiring harness for your Curt Triflex Brake Controller # C51140. When your controller is properly wired for your vehicle side trailer connection, then you simply add a breakaway kit to your trailer in case your vehicle becomes disengaged from your trailer. If you don't yet have the breakaway system, I recommend the Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger...

• Trailer Break Away Switch is Draining Trailer Battery
  
• There is always going to be power going to the breakaway switch but that power will not go anywhere unless the pin is pulled. And if the pin is pulled your brakes would lock up. There could be something else that is draining the battery. Check all the wiring to the battery, brakes, and break away system. You will be looking for loose or broken wiring, corrosion, and loose connections. Clean off dirt and corrosion on the wiring/connectors. You should also know that the 12 volt circuit...

• Replacing Breakaway System Switch on Lacrosse Travel Trailer
  
• All the breakaway switches we offer serve the same function and are pretty much interchangeable as long as the switch on your trailer is normally closed. The circuit is normally closed until the switch pin is pulled, which closes the circuit and allows the voltage from the battery to reach the trailer brakes. Just because the system you currently have uses a switch from Bargmann, doesn't mean your replacement needs to be of that brand too. The Hopkins replacement breakaway switch, part...

• Replacement Breakaway Switch for a 1991 Dutchman Camper Trailer
  
• We do not carry the Kool-RV products so any of replacement pins are not a for sure fit because they have not been tested together. What I recommend is to go ahead and replace the the whole switch since it is not very expensive. You could use # 420000 that you have referenced or another switch like # HM20010.

• Replacement Trailer Break-Away Switch for a Hopkins Engager Trailer Break-Away Kit
  
• The Replacement Tekonsha Trailer Breakaway Switch, item # 420000, is compatible with Tekonsha breakaway kits. The item # 20099 is a Hopkins breakaway kit, and it uses a Hopkins switch. The Tekonsha switch may work but for safety purposes we recommend replacing the switch with the original manufacturers switch. We offer two different Hopkins replacement switches with different lengths of lead wire. They are the Hopkins Replacement Break-Away Switch, 7 inich Lead Wires, item # HM20010, and...

• Should a Rusted Trailer Breakaway Switch be Replaced
  
• The pin that keeps the contacts inside a break away switch is plastic or otherwise a material that does not conduct electricity. As long as the contacts on the inside are not rusted the switch will continue to work. There is a way you can test it and I have linked an FAQ that shows how. Given that rust spreads it sounds like it would be a good idea to replace the switch. You can use any switch, like # 420000, that you have referenced. If the wiring to and from the switch is removed then...

• Can Replacement Breakaway Switch # 420000 Be Used with Any Breakaway System
  
• For the most part, all breakaway situations work the same way. There are a few exceptions but they are not common. If your existing system used 2 wires like # 420000 then you can use it or any similar switch. I have included a link to all of the breakaway switches we carry.

• Troubleshooting Camper Breakaway Switch with Pin That Will Not Come Out
  
• I am glad you were able to safety return home after your camper's brakes locked up. It sounds like your breakaway switch could be corroded internally. That would explain why the pin would not come out. It is possible that same corrosion caused a short inside the switch that in turn caused the breakaway battery to apply the trailer brakes. We can help you with a complete new breakaway kit like # 50-85-315 or the Tekonsha unit you referenced, part # 20020. We also offer breakaway switches...

• I can help you wire the Replacement Tekonsha Trailer Breakaway Switch # 420000 and the accompanying diagram shows exactly how it will be wired; I have also added a link to a video which shows it being installed. The white wire is a ground wire and the other two wires are interchangeable. One will be spliced from the from the switch and blue trailer brake wire that is running from the trailer connector to the trailer brakes. The other wire will be spliced to the blue brake wire coming...
