Can Rotary Dimmer Switch with 2 Wires Replace Switch with 3 Wires

Question:

I have a 3-wire rotary 12 volt dimmer switch on my Lance trailer for the dinette area. I see you have 2-wire version for sale but I dont see a 3-wire listed. Is this something you can provide?

The Rotary Dimmer Switch # 37215235 is the only one in that style we have, but we also carry some other options which you can see linked below.

The third wire on your current switch will be for the ground, and from my understanding JR Products is relying on the ground from the light to count as the ground in the second wire which is why they only have 2. If you aren't entirely comfortable with this method then here are the other options we carry:

- RV LED Light Side-Slide Dimmer Switch - White # 37205-12325
- RV LED Light Side-Slide Dimmer Switch - Black # 37205-12315

These are a different style but they do have the 3 wires like what you currently have.
