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.
