Open during play makes sense, the contacts are probably wired to short across the cartridge output connections to mute the output. If there's two switches as you say, they are probably wired in parallel, so either switch closed will lead to silence.
I can't directly make sense of having two switches, either, but maybe the TT motor can get shut off when the mechanism isn't in a change cycle, so the mech is in play position, and they wanted the system to be immune from hum, noise from being bumped, etc., in this state?

Working on restoring a non-selective ristaucrat and I'm puzzled about 2 cut off switches for the tone arm wiring. One cut off switch is a combination leaf switch in the front that also serves as the turntable power cutoff if no credits remain. The second cutoff is also a leaf switch that is currently activated during the record change. What puzzles me is that these switches are closed -making connection- when the system is inactive (switch 1 when power to the tt motor is cut b/c of no remaining credits and switch 2 during record exchange) while both these switches are open during record play. If anyone has any insights in this please let me know. I can find ways to bypass these switches but I prefer to hook everything up as intended. I suspect that leafswitch #2 should be closed during playing and should be opened during the record exchange. Those leafs were bent apart by a previous owner who did some creative bypassing. The other thing I don't quite get is why there would be two c ut-off switches for the sound. Wouldn't one suffice? Thank you! Hans
