Abstract
A trip-free manual reset thermostat includes a first fixed contact and a second fixed contact for an electric circuit and a bridging contact having a first end and a second end in contact with the first and second fixed contacts, respectively, in a normally closed position. The bridging contact is tripped open and is not in contact with the first and second fixed contacts at a predetermined higher temperature. When a pushbutton is in a depressed position, the bridging contact is pressed toward the fixed contacts and the second end of the bridging contact is caused to pivot around the first end of the bridging contact. The thermostat does not require a narrow manufacturing and assembly tolerance to achieve a trip-free function and has a simpler structure and is easy to manufacture.
