The circuit comprises an oscillator circuit, and its oscillation frequency is 100kHz. It starts oscillation when the metal block closes to the oscillator circuit. When the oscillation loop is not affected when the supply voltage varies between 3 ~ 9V. The circuit can not only be used as a mechanical terminal switch, but can also be used as speed transmitter, when machine parts pass through the air gap, it will generate a pulse.
