Wireless Telegraph Key
- Description (Brief)
- Telegraph keys are electrical on-off switches used to send messages in Morse code and can spark when the circuit opens. This wireless telegraph key features a large disc on the knob to protect against the accidental shock. Until recently, “wireless” meant radio and early wireless equipment often used high voltages.
