  • Patent number: 4667066
    Abstract: A plunger operated switch having a normally closed pair of contacts and a normally open pair of contacts, the normally closed pair of contacts including a movable contact carried on the free end of a first cantilevered resilient leaf member biased to separate the contacts, the normally open pair of contacts including a movable contact carried on the free end of a second cantilevered resilient leaf member biased to bring the contacts together. An actuator projection on the plunger bears against the first leaf member at a location substantially aligned with the contact thereon, and a further actuator on the plunger bears against the free end of the second resilient leaf member. The plunger is biased to urge the normally closed pair of contacts closed and the normally open pair of contacts open by a spring which is sufficiently strong to overcome the biases of the resilient leaf members.
