Claims

[Scope of utility model registration request]

A main switch comprising: a first switch connected to a commercial power source; and a second switch that is connected to the first switch and turns on during a transient state when the first switch is turned on, and then maintains an off state; A relay switch provided between the output end of the switch and the controlled device, a first control terminal to which a pulse to turn off the relay switch is input, and a second control terminal to which a pulse to turn on the relay switch is input. a control logic circuit, the control logic circuit generating a signal having a longer duration than the signal supplied to the control terminal of the control logic circuit in response to the turning on of the first switch; CR applied to the second control terminal of
A power supply control device characterized by comprising a time constant circuit.
