Claims

[Scope of utility model registration request]

A detection circuit consisting of the primary coil of the current transformer, a main circuit consisting of a triac that charges the voltage induced in the secondary coil of the current transformer and is driven only during this discharge period, a load A connected to the detection circuit, and the main circuit. A load B connected to the load B, a power supply connected to the load A and the load B, an element that detects the opening and closing of the door, and a three-way contact element that connects a common terminal to this power supply and switches between the detection circuit and the main circuit. A binary circuit that switches sequentially in conjunction with the output of Featured load control device.
