The push-to-talk switch must be depressed for which actions?

Explanation:
In a sound-powered telephone, there’s no separate power to drive the circuit. The push-to-talk switch acts as the gate that closes the two-wire line so signals can flow in both directions. When you depress it, your microphone is connected to the line so you can transmit, and the receiver path is also completed so you can hear the other party. When it’s released, the circuit opens and neither speaking nor listening can happen. So the switch must be held down to allow both transmitting and receiving.
