I picked up a set of Spal switchs for power windows (universal kit 33040122) and I'd like to know if anybody can tell me what the pin-outs are.

They are lighted momentary on/off/on switches.

On the back are the letters; A, B, C, D, E, and L

Thanks

Thanks!

Is the Spal manual available on the net? I looked at the Spal web site and couldn't find anything.

Is the reason for two different grounds that one is specifically for the light?

Are the switches such that when one "motor" output is +12 volts, the other is connected to ground?

Can the switch directly handle the amperage for power windows in a Honda Civic (I'm retrofitting JDM power window units) or should I drive them through relays?

hi,

manual came with a power window kit.........the reason for the two grounds is so that the switches can be used in a master (driver)/slave (passsenger) system, i.e. 3 switch setup.......yes, the switches reverse polarity on the motor wires..... don't see why they couldn't, seems that spal runs a 25 amp fuse for a two window system.

hope this helps
