ABSTRACT:
In a push button actuated, bimetal controlled, current overload switch capable of undergoing trip-free release and including a bimetal strip disposed in a housing, an angular contact bridge disposed in the housing and forming part of the current path provided by the switch, a switching rod mounted in the housing for axial movement relative thereto and having one end extending out of the housing, a switching rod extension mounted at the other end of the rod and within the housing and arranged to bear against the bridge, and a spring disposed to maintain a spring force between the bridge and the extension, opening of the switch by actuation of the rod is made possible by the provision of an obliquely extending lever disposed in the housing, having one end pivotally secured to the housing, having its other end engaging the bimetal strip, and located in the path of travel of the extension during axial movement of the rod into the housing for enabling such movement of the rod to displace the lever in a direction to change the switch from a switched-on state to a switched-off state.
