Rock~Ola 1438 Electrical Question

Hello,

I am getting ready to restore a Rock~Ola 1438 and I have a couple of
questions. At the back of the machine where the volume and reject
switch are located there is a blade switch what I can can't find a
reference to. see: http://www.pasetta.net/rockola/volume_reject.jpg

Can anyone help identify this for me and tell me what it is supposed
to be wire to?

I am also looking for the following parts:

1) The male plug that goes from the Amp to the power supply
2) The plastic select button
3) The dome extrusion for the light in the top back of the cabinet
4) The "Rock~Ola" name badge that goes on the done mentioned above

Thanks you for the assistance. -Mike

Thanks Charley,

Interesting, there is a hole in the side to activate it. I am
assuming that this is there in case you can not reach the other switch
directly next to it that would typically be against a wall. -Mike
