Parts Needed For Wiring 2 Light Switches at 2 Doors To Operate Lights Like a 3-Way Switch

Question

Question:

I have an enclosed trailer that has 2 interior LED dome lights with only a single switch by the side door. I also have an exterior LED 6” bar light over my rear drop down door, with a single switch just inside the rear door on the wall. I want to be able to turn my interior lights off/on from the side door location and also at the rear. Do I need a double switch at rear? One to work as a 2 way with side door switch and the other to operate the existing light over the rear drop door? How would I wire them? I do have a breakaway battery and its own 12V battery inside the trailer. Thanks

I recommend placing 2 of the Single Rocker Switch # 37212635 at both the front and rear door with the Double Bezel RV Switch Faceplate # 37213615 at each location. This way you will be able to control both lights from either location. Each switch is rated for up to 10 amps of power with up to 14volts.

Each switch has 3 terminals the center terminals are for connecting to your input power or the 12 volt light. The outer terminals are for connecting to each switch as travel wires. So you will have one switch at either door supplying power for both switches on the center terminal. The 2 outer terminals for both terminals will run to the corresponding 2nd switch at the other door. At these switches you you will run the power wire to the light assemblies themselves. This way power will be able to run from one switch to the 2nd across the travel wires and then to the light itself when both the front and rear switch are in the same position. By flipping one of the switches it breaks the connection and no power will go to the light.

For your 2011 Keystone Hornet, you can use the Single Rocker Switch #37212635 in white, or #37212625 in black to in two different locations to create a 3-way switch that can be controlled in separate locations.

It depends on what you mean by that style. The #37212135 SPST is single pole single throw (SPST), which you are not going to find in 3-way. If you are looking for a single rocker switch that can be wired for 3-way use, the Single Rocker Switch…

We sure do! You'll need switch #37213435 which works with the #37213625 Triple Bezel Face Plate you'd referenced. JR Products confirmed the compatibility for me.

Answer 4

I have a solution for you that is very similar but the switches of the JR Triple Switch setup part #37212025 are not removable. Instead you'd want the Triple Bezel RV Switch Faceplate #37213625 and the part #37212585 for the SPST switches and the…

The only way you could power interior dome lights on a trailer without it being connected to a tow vehicle would be to power the lights with a battery like a breakaway battery. How you choose to wire up the batteries will in the end be up to you, but…

Answer 6

The only pin that should be continuously showing 12V power on the 7-Way connector on your vehicle is the 12V power circuit which is normally the black wire but not always. In 7-way wiring the 12V auxiliary power feed is carried on the contact at the…

Answer 7

You can still have 12V power coming from your towed vehicle but if you'll be installing the Progressive Dynamics 4100 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel #PD4135K then you'll also need the Progressive Dynamics…
