AC contactor technology development
Vacuum contactor: Vacuum contactor is the contact system using vacuum degaussing chamber contactor.
with permanent magnet drive mechanism to replace the traditional electromagnet drive mechanism and the formation of a micro-power contactor.
Permanent magnet contactor: permanent magnet AC contactor is the use of magnetic poles repulsion, the opposite sex suction principle
Semiconductor contactor: The semiconductor contactor is a contactor that performs current operation by changing the conduction state and the open state of the circuit circuit.
