ABSTRACT:
A protection mechanism for a switch device includes a disk rotatably connected to an inside of the case and two ends of a pull member are pivotably connected between the disk and the switch member pivotably connected to an open top of the case. One of the two ends of the pull member lifts the bimetallic plate to set the “OFF” status when pivoting the switch member. A push member has one end movably engagged with an upward groove in an inside of the case so as to push the bimetallic plate to contact one of two terminals, and the other end of the push member is pivotably connected to the disk. The push member is pivoted an angle to produce a space between the push member and the bimetallic plate when the switch member is pivoted to “ON” position and the space allows the bimetallic plate to be completely deformed when overload.
