ABSTRACT:
An exemplary electromagnetic induction switch includes a coil, a magnet suspended in the coil, a rectification circuit, and a relay-switch. The coil is connected between two input terminals of the rectification circuit. Two output terminals of the rectification circuit are respectively connected to two relay leads of the relay-switch. One of two switch leads of the relay-switch is connected to a working circuit, and another one of the switch leads of the relay-switch is connected to the working circuit via a power source, thereby controlling the power source supplying power to the working circuit.
