Viewing the tooth-wheel end the according (fast) switching contacts (like is contact 5) and levers and also the mechanism to prevent that channel 0 being selected, the audio will then be switched-off by short-circuiting contact 7 against ground. The blank-tooth is preventing that channel 32 can be operated.

Its a very clever piece of mechanism, I like how the repeater indicator aligns with the setting of the channel. I assume that the large wheel is on the shaft of the receiver's tuning capacitor, which is why all the positions are in a 180 degree segment?
