Remote control wall switch socket contacts required to achieve, and electromagnetic contactor Contactor, pneumatic and hydraulic contactors contactors, three different voltage is divided according to AC and DC and semiconductor several. Commonly used mostly AC electromagnetic contactor, AC contactor is a solenoid, mountain-shaped static and dynamic core, moving main contact together, moving together, moving off assistance and contact interrupter system and other major components. The principle is that when the core of the coil is energized to produce suction, the armature (or moving magnet) pull, since the contact support member fixed to the armature with armature motion TV wall switch to the core (yoke), the contacts together with the support member assembly thereon contacts with the movement, in contact with the stationary contact, the circuit is turned on. Once the trip coil current, voltage suddenly disappeared or significantly reduced proof wall switch, armature yoke from the rebound in the spring, at the same time, the primary and secondary moving contact from the fixed contact of the circuit off.
