Abstract
A overload protection switch with a reverse restart switching structure that has a seesaw lampshade provided with a protruding block which extending downward from the outside of the seesaw lampshade to ensure that the seesaw lampshade and the moving rod are accurately positioned in the ON and OFF positions in the housing to form a three-stage switching type with bidirectional positioning and forms an overload protection switch that can continuously maintain sufficient insulation distance and does not reduce the insulation distance due to fatigue decay of the binary alloy conductive plate.
