M RelayRight - 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
