PROBLEM TO BE SOLVED: To provide an electronic device capable of cutting/feeding the electric power to a primary power supply circuit by the automatic operation, directly cutting the power supply to the primary power supply circuit easily by the manual operation based on an operator's intention, and securely reducing the power consumption of the primary power supply circuit to zero when not used. SOLUTION: The switch device S1 comprises an operation member for switching the position of a switch among a manual on-position, a manual off- position and an automatic on/off position where the switch can be turned on/off automatically, and a drive source for the automatic operation of the switch. At the automatic on/off position, the drive source is driven with a signal from a control circuit 28 or with the power supply from a capacitor 30, and the switch is automatically turned on/off. The device enables the automatic operation of feeding/cutting the power to a primary circuit 21, and also enables the manual operation of feeding/cutting the power to the primary circuit 21 by turning on/off the switch by the manual operation of the operation member. |
