ABSTRACT:
A snap action switch including a switch in incipient form. The switch comprises a contact having a cut-out tongue mounted on a post with the tongue bent to form a spring, the post being one terminal. The other end of the element remote from the tongue end initially contacts an exposed second or third terminal above or below the other end. When an actuator or nose from a resilient body acts against the surround adjacent the tongue end, force is exerted against the contact. The contact snaps from the initial connection between the nose and one of the second or third contacts to the other. When the resilient body relaxes, the nose resumes its original position and the switch snaps back to resume a connection between the post and the initial connection with the second or third terminal.
