ABSTRACT:
A temperature switch includes a housing, a movable contact mounted in the housing for movement between a first and second position, a fixed contact mounted in the housing and operatively associated with the movable contact for engagement with the movable contact in the second position, a heat sensitive plate mounted in the housing and which constitutes an amorphous metal member with a highly expansible metal wherein the amorphous metal member is exposed to a predetermined region, the temperature of which is to be determined wherein deflection of the heat sensitive plate is caused by a temperature change in the region for movement of the movable contact with respect to the fixed contact.
