  • Normally-closed switching means with over-stroke compensation
    Patent number: 4386245
    Abstract: A normally-closed switch in which a movable contact member is normally held in contact with a fixed contact member by spring-load of a plate spring member. When an operating member is pressingly operated, the plate spring member is resiliently displaced into a position where the plate spring member comes in contact with a stopper member. The movable contact member is thus separated from the fixed contact member. When the operating member is pressed further, the plate spring member is not displaced, but a resilient member is compressingly deformed, thereby compensating for the over-stroke of the operating member.
