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.

3. An electronic device comprising:
-
a working circuit; a power source connected to the working circuit configured for supplying power to the working circuit; a relay-switch controlling the power source supplying power to the working circuit, the relay-switch comprising a relay portion and a switch portion; a coil with a magnet suspended therein, during movement of the electronic device, the magnet moves relative to the coil so that the coil generates an alternating current; and a rectification circuit comprising two input terminals connecting to two opposite terminals of the coil to receive the alternating current and converting it to a direct current, and two output terminals connecting to two opposite leads of the relay portion of the relay-switch to output the direct current to the relay portion to thereby short the switch portion of the relay-switch for allowing the power source to supply power to the working circuit. - View Dependent Claims (4, 5, 6, 7)
