Background
The utility model relates to a relay electrical control circuit device for products such as corridor switch, public regional lamps and lanterns. In current relay control circuits, the control circuit and the relay generally share a power supply. The current of the circuit is larger no matter the relay is attracted or not attracted. Particularly, in the circuit using the zener diode, please refer to fig. 1, when the relay is not engaged, the total current I of the circuit is IM + IW, where IM is consumed by the main circuit, IW is the current flowing through the zener diode, and when the relay is engaged, the total current I/═ IM + IW + IJ.
