Description
Technical Field
The invention relates to an energy-saving electromagnetic switch.
Background
The electromagnetic switch is an automatic switch using an electromagnet as a power device, and the electromagnetic switch in the prior art generally comprises the electromagnet, a movable iron core and a switch contact, and basically adopts a working mode that the attraction of the electromagnet and a corresponding reset mechanism are utilized to realize the reciprocating motion of the movable iron core, and the reciprocating motion of the iron core further triggers the closing and opening of the switch contact, so that the switch function is finally realized. The disadvantage of such conventional electromagnetic switches is that the electromagnet must be kept energized for the entire closing time of the switch, wasting energy and not benefiting the service life of the switch.
