Working principle and wiring diagram of electromagnetic relay
Jul 30, 2018

The working principle of electromagnetic relay:

Relays are divided according to the working principle and can be divided into temperature relays, time relays, high frequency relays, solid relays, electromagnetic relays and other different types. Here we take the electromagnetic breaker as an example: the electromagnetic relay consists of an armature, a coil, a contact spring and an armature. After the power is applied, the current flows through the coil. Under the action of the electromagnetic effect, the armature is close to the iron core, and the dynamic and static contacts are closed. After the power is cut off, the static and dynamic contacts are separated.
