Thought I would provide a bit more info on these switches:
They are made by Carling. The switches used by ARB are the incandescent version. Carling also offers LED versions with differing color LED colors for on/off, etc.
The part number for the ARB (incandescent) switch is ‘V1DAJ66B-00000-000’, this is the switch only, not including the actuator (I.E. switch cover). I ‘think’ the actuators ARB used are Contura II’s.
Most Contura actuators are interchangeable on the V-series switches. By this I mean any Contura II, III, IV and V actuator can be used on a V-series switch. I don’t believe this applies to the X and XI, as they are different switch. To date I’ve never been able to find the Contura ‘laser etched’ actuators. Hopefully some day.
I won’t go into figuring out the circuits or building part numbers as (for me) that was challenge. I’m sure tons of other folks can do a much better job of explaining that.
I know of two sources for small quantity purchases of Carling Contura switches and actuators. As already mentioned waytekwire.com seems to be the most common. When I checked waytek a few years ago, they didn’t offer the LED versions of the V-series switches (which I wanted). They also didn’t offer a wide assortment of actuators. Again, this was a few years ago, I’m guessing things have changed since then.
I stumbled upon a guy in Alaska named Shawn. He offered a fairly wide assortment of the Contura V-series switches (incandescent / LED) and actuators. I picked up everything though him.
Hope this helps,
Kent
