Abstract:

A thermally actuatable switch construction having a relatively thin and long and wide housing provided with a similarly shaped chamber therein and a pair of terminals extending into the chamber. A contact member is disposed in the chamber for respectively engaging and thereby electrically interconnecting the terminals together when the contact member is in one position in the chamber and for respectively moving away from contact with the terminals to thereby electrically disconnect the terminals from each other when the contact member is in another position in the chamber. A temperature sensitive member is disposed in the chamber and is adapted to collapse when the same is at a predetermined temperature. A biasing member is disposed in the chamber and is operatively associated with the temperature sensitive member and the contact member to hold the contact member in the one position thereof as long as the temperature sensitive member is in an uncollapsed condition thereof, the contact member extending substantially from side-to-side in the chamber.
