A protection mechanism for a switch device includes a pivotably member pivotably connected to an underside of the switch member pivotably connected to an open top of the case of the switch device. The pivotable member includes a shorter tongue and two rods. An end of the bimetallic plate is inserted between the two rods and the tongue so that when the switch member is pressed on one end, the bimetallic plate is lifted to set the switch device to "OFF" position. When the switch member is pressed on the other end, the pivotable member is lowered and the tongue pushes the bimetallic plate to "ON" position. The pivotable member is pivoted an angle and moved toward a space in the case so that the tongue is shifted a distance such that the bimetallic plate is not stopped by the tongue when it is deformed due to overload.
