Low-voltage permanent magnetic vacuum switch

A low pressure vacuum switch mainly comprises a low voltage switch bubble and a permanent magnetic operation mechanism. The low voltage vacuum switch bubble is fixed on a switch base, and a moving contact is connected with the base through a operation rod. The pull-in and separation of a permanent magnet and the base is controlled by the on and off of the current in a coil, thus accomplishing the breaking and closing of a vacuum switch contact. The switch has the prominent advantages of safety and reliability, high current carry ability, good arc quenching performance, low bounce, stable open and close timing and long service life, etc. The operation reliability of switches and electric appliances can be effectively improved by the switch in a power supply system.
