Abstract
A mechanical switch comprises a pusher rod, a movable member movable from one position to another position in response to the depression of the pusher rod, a movable contact carrier normally held in position to connect a pair of contact elements on respective terminal members to each other therethrough so long as the pusher rod has not yet been depressed, and a return biasing spring for urging the movable member to the one position. The contact carrier is, as the movable member approaches the another position in response to the movement of the pusher rod, snapped to move from the position in which the contact elements are connected to each other to a different position to disconnect or open the circuit between the terminal members. The pusher rod has an abutment defined therein to forcibly separate the contact elements from the contact carrier in the event that the contact elements have been fused to the contact carrier.
