Are the switches "alternate action"....ie, push on/push off? How many poles are on each switch?

I'm not quite understanding your question regarding the headphone amp.

Best,

Tape machine remote switches are typically "momentary" action, sort of like a doorbell button. IOW, you have to hold them down for the contact to be completed.

To do audio switching without a bunch of extra circuitry, the switches need to be "latching" "push-on/push-off". Also, for balanced audio lines, each switch needs to have two poles, as in a DPDT switch.

Best,
