I have my trailer gutted and am re-doing some 12V
the below pic shows ground and hot wires going from the distribution box then giving a wire off to a kitchen light and USB over to the street side; a branch to a fan; then to a dinette light in front; then to a switch on the curb side which goes to three overhead lights down the center. My questions concern the switch to the three center lights:
1. Is this wired correctly? I want to be sure turning the switch off and on won't affect the other lights in the circuit. Also, for the ground, can I take a short cut and instead of the ground going all the way back to the switch after connecting with the three center lights, can I just connect it to the ground back to the ground wire in the ceiling center right after the front (bottom) light?
2. What kind of switch - SPDT?
