M Relay

Right - No Jumper.

All switches open on the stack other than a set of contacts with a Maroon/White wire and a Maroon wire. This set is normally closed. I think this was the lower set on the stack with two sets of switches.

These pictures are crap - sorry - I think they have to be at a higher resolution ;

No jumper



Stack of 3 switches = All open



Stack of 2 switches= One Normally Open the other Normally closed
