ABSTRACT:
A protection mechanism includes a first member connected to a switch member pivotably connected to an open top of a case so as to lift a bimetallic plate when the switch device is set to an “OFF” status, and a second member that is pivotably connected to an extension board extending form the switch member. The second member is located above the bimetallic plate and pushes the bimetallic plate downward to set the switch device to an “ON” status. The second member can be pivoted counter clockwise when the bimetallic plate is deformed upward and will not stop the deformation of the bimetallic plate.
