摘要： A noise decreasing type electromagnetic switch includes a buffer disposed between a stationary core and a contact spring to electrically support a shaft and the stationary core. The buffer includes a buffering space therein. Accordingly, impact caused at the stationary core and the shaft can be effectively absorbed even by the buffering space as well as an elastic force of the buffer. The buffer is inserted in the stationary core for coupling so as to be prevented from being separated during operations, resulting in maintaining long-term durability. Also, the buffer may support the stationary core and a metal plate, whereby an assembly process can be simplified.

摘要： A sealed cased magnetic switch includes: a first contact pressure spring having one end supported by the movable contactor and applying an elastic force to the movable contactor to provide a contact pressure in a direction in which the movable contactor is brought into contact with the fixed electrode; a spring seat member supporting the other end of the first contact pressure spring and fixedly installed on the driving shaft; and a second contact pressure spring having a diameter larger than that of the first contact pressure spring and applying an elastic force at an outer position in a radial direction compared with the first contact pressure spring to the movable contactor in a direction in which the movable contactor is brought into contact with the fixed electrode.

摘要： A noise decreasing type electromagnetic switch includes a buffer disposed between an end of a stationary core and an end of a movable core facing the end of the stationary core so as to allow the movable core 150 to be elastically supported with respect to the stationary core. Accordingly, when the movable core contacts the stationary core, the buffer can be pressed and transformed to decrease impact and noise. Also, when the final operation is completed, the stationary core and the movable core are closely adhered, a performance of an actuator can be maintained.
