Description

Magnetic latching relay with microswitch

Technical Field

Background

The magnetic latching relay is a novel relay developed in recent years and is also an automatic switch. As with other electromagnetic relays, it acts to automatically turn on and off the circuit. The magnetic latching relay has the advantages that the normally closed state or the normally open state of the magnetic latching relay completely depends on the action of permanent magnetic steel, and the switching state of the magnetic latching relay is triggered by pulse electric signals with certain width to complete the switching. The magnetic latching relay is divided into a single phase and a three phase. According to the introduction of related information, the contact switching current of the magnetic latching relay on the market can reach 150A at most; the control coil voltage is divided into DC9V, DC12V, etc. The service life of the general electric appliance is 10000 times; mechanical life is 1000000 times; contact drop <100 mV. Therefore, the electromagnetic relay has the characteristics of power saving, stable performance, small volume, large bearing capacity and superior performance compared with the common electromagnetic relay. The magnetic latching relay is normally kept in the contact open/close state by the magnetic force generated by the permanent magnet. When the contact of the relay needs to be in an open or close state, the relay only needs to excite the coil by positive (negative) direct current pulse voltage, and the relay completes the state conversion of opening and closing instantly. Normally, when the contact is in the hold state, the coil does not need to be energized, and the relay state can be maintained by only the magnetic force of the permanent magnet.
