How should this coin door switch be wired up for my Williams Comet? I have 2 white wires and a black & red wire.

On the switch there's COM/ NC/ & NO options.

Whites both connect to NO.

Wrong (although in reality doesn't really matter)

Look at page 21 of your schematics

The Black/Red wire is the memory protect signal back to the MPU...That goes on the NO

The white wires are grounds....They go on the COM
