ABSTRACT:
A switch device includes a body with a switch member pivotably connected to a top thereof and two terminals extend through an underside of the body. A first contact point is connected to one of the terminals and a bi-metallic plate has a first end fixed to the other terminal. A second contact point is connected to an underside of a second end of the bi-metallic plate and located above the first contact point. A pull member has an upper end pivotably connected to the switch member and a lower end of the pull member supports the underside of the second end of the bi-metallic plate. An upper end of a push member is pivotably connected to the switch member and a lower end of the push member is in contact with the bi-metallic plate. A spring is biased between the push member and the body so as to provide a push force to the push member. The push member pushes the bi-metallic plate toward the second terminal when pivoting the switch to “ON” position, and the pull member lifts the bi-metallic plate when pivoting the switch to “ON” position. The push member is pushed by the deformation of the bi-metallic plate to pivot the switch to “OFF” position when the switch device is overloaded.
