Well, I want to add an accessory to my 2001 Corolla, so I thought I'd just get a switch from a breakers and put it into an empty hole.
However the switch has 8 pins and I've figured out that three are +12V and one is Ground. When I wire up the switch like this, it illuminates fine, but when I press it, none of the spare wires do anything sensible like switch from 0 to 12v or vice-versa.
This is just a fog light switch so I'd be very surprised if it was sending some complicated multiplexed signals around. Any ideas please?

I figured it out in the end. The switch actually includes a latching relay. You need to tie 4 pins to +12v and another two to GND and then pin 1 is the latching O/P.
Bizarre to have so much built into the switch!
