摘要：
A thermostatic switch has a housing and a temperature responsive bimetallic disc located in the housing and responsive to a predetermined temperature for exerting a flexing action. A fixed contact member is located in the cavity along with a movable contact member which is biased and movable between a switch-closed position in which it makes electrical contact with the fixed contact member and a switch-open position in which it is spaced from the fixed contact member. An actuating member is located in the housing, and is responsive to flexing movement of the disc for moving the movable contact member from the switch-closed position to the switch-open position. A hook portion is mounted within the cavity of the housing, the hook portion engaging an arm portion of the movable contact member upon the movement of the movable contact member to its switch-open position and entering an opening of the arm portion for retaining and maintaining the movable contact member in its switch open position.
