A FIXED CONTACT IS LOCATED BETWEEN THE TWO SUPPORTS. IN AN INITIAL OPEN POSITION OF THE SWITCH THE MOVABLE CONTACT IS SPACED FROM THE FIXED CONTACT. WHEN THE SWITCH IS CLOSED THE MOVABLE SUPPORT IS MOVED SO AS TO APPLY PRESSURE PLACING THE MOVABLE CONTACT UNDER COMPRESSION. THIS COMPRESSION CAUSES DEFLECTION OF THE MOVABLE CONTACT SO THAT THE MOVABLE CONTACT ENGAGES THE FIXED CONTACT.
