  • Wiring for Carlingswitch Contoura rockers

    I am rewiring my dash panel and I bought a bunch of the illuminated Carlingswitch Contoura switches. I am baffles why the rear of these switches have three spade connections for a single pole on/off switch. Shouldn't they just have two? Is one of those three a negative so the backlight works? Help!

    One is pos. pwr. IN, another is pos. pwr. OUT, and one is a neg. for the backlighting. I have a wiring diagram for them, but I don't have a scanner to scan it.. and I really can't make heads or tails from it anyways.

    The easiest way to figure it out is to make a quick test circuit. Hook a wire to the pos. of a battery and a wire to the neg. terminal. Hook a little test light to one pole on the switch, hook the pos. from the battery to another pole on the switch and flip the switch. Do trial and error until you have it figured out. Once you have the 2 pos. poles figured out (the test light is switching on & off), the other one is the neg. for the backlighting on the switch.

      Heres a pix of the back of my switches. I have an extra pole for backlighting (custom switches with 2 separately powered lights) which is what the blue wire is hooked into.

      -The blue arrow is pointing to the neg. terminal

      -The red arrow is pointing to the pos. IN terminal

      -The yellow arrow is pointing to the pos. OUT (switched) terminal

        OK, I got that, piece of cake. Now another question: On a three position switch On/Off/On, what is the schematic?

          I ask because it does not appear to follow the same logic as the two position, seeing as how I almost started a fire in my garage testing it. [V]

              Are you referring to single pole, dual throw type switch? I have (or can draw) schematics for most types of switches. I was at one time a dealer, but threw away all my dealer catalogs about 3 weeks ago while attempting to clean my garage out.
