Background
The relay is an automatic switch element with an isolation function, is widely applied to remote control, remote measurement, communication, automatic control, electromechanical integration and power electronic equipment, and is one of the most important control elements. Relays generally have sensing mechanisms (input parts) that can reflect certain input variables (e.g., current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); an actuating mechanism (output part) which can realize the on and off control of the controlled circuit; between the input part and the output part of the relay, there is also an intermediate mechanism (driving part) for coupling and isolating the input quantity, processing the function and driving the output part.
The magnetic latching relay is a new type developed in recent years, and has an automatic switching-on and switching-off function on a 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. Under conventional circumstances, the stationary contact is riveted on the stationary reed, and the stationary reed position is relatively fixed, and when being converted into the normal close by normally opening, the movable contact striking stationary contact, the stationary contact can produce the separation and the closure of very short time because of the counter-force of reed.
