Abstract: An electrical switch has a fixed contact and a moving contact moving between a first position in contact with the fixed contact and a second position not in contact with the fixed contact. An operating mechanism moves the moving contact and includes a resiliently biased presser resiliently pressing upon the moving contact while riding in opposite first and second directions past a barrier associated with the moving contact, and a spring having first and second parts acting on first and second sides of the presser to maintain the presser in a neutral position and providing extra biasing force to assist the presser in moving faster upon riding past the barrier.

Abstract: An electrical switch has a housing having an opening, fixed contacts located in the housing, a switching member supported in the housing for movement, and at least one moving contact movable by the switching member for movement to come into contact with and out of contact from the fixed contacts. An actuator is disposed in the opening for movement to actuate the switching member and in turn the moving contact. A gap is formed between the actuator and the opening that surrounds the actuator. A rubber deformable seal is connected across the opening and the actuator to seal off the gap, thereby avoiding entrance of foreign matter through the gap into the housing.
