Abstract
A switch assembly is provided that comprises a switch having a normally open contact and a normally closed contact which is electrically connected to the normally open contact and which is located either within the same housing as the normally open contact or a separate housing. The housing(s) may be mounted onto a latch assembly which, in turn, is mounted onto a switch operator, thereby closing the normally open contact. If the latch assembly becomes mechanically disengaged from the switch operator, thereby rendering the normally closed contact non-operational, the normally open contact will open, thereby opening the circuit to a machine performing a controlled function. The user, noticing the stoppage of operation, will then be alerted of a malfunction within the switch assembly.
