A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has a second conductive layer protruding from the bottom layer top surface and spaced apart from the first conductive layer. The conductive member is rollably disposed in the chamber and is limited by the second conductive layer for forming a current path with the first and second conductive layers.

A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The bottom layer assembly has a bottom groove communicating with the chamber. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has at least one second conductive layer disposed in the bottom groove. The conductive member is rollably disposed in the chamber for forming a current path with the first and second conductive layers.

An overload relay is disclosed in which a single operator coil is controlled for both tripping and resetting. A permanent magnet and a spring make the device bi-stable, so the coil may be unpowered when in the trip and reset states. Energization of the coil overcomes the magnet to allow tripping, while energization in an opposite direction adds to the magnet force to reset the device. An electromagnetic activation path overrides a mechanical activation path for electromagnetic tripping despite attempted manual resetting. The device may be pulse width modulated to reduce power consumption

An integrated switch is provided in the present application, comprising: a housing; a first circuit board, arranged in the housing; a movable stand, movably connected in the housing; a contact component; a second circuit board, arranged in the housing and connected with an inner wall thereof, and electrically connected with the first circuit board; an electric brush, arranged between the movable stand and the second circuit board, having one end connected with the movable stand and the other end slidably connected with the second circuit board, driven by the movable stand, the electric brush has a connection state after sliding to a first position of the second circuit board, and a disconnection state after sliding to a second position of the second circuit board, and the moving contact shifts from a power-on state to a power-off state after the electric brush slides to the disconnection state.

A pressing structure includes a support frame and a pressing element. The pressing element is mounted to a bottom surface of the base plate. The pressing element includes a pedestal and a cushion element. The pedestal has a base board. A bottom surface of the base board protrudes downward to form a pressing block. A bottom surface of the pressing block is recessed upward and gradually arched outward from top to bottom to form a first pressing face. The rocker component has a base portion. The first pressing face is in contact with the base portion. The cushion element is mounted on the pedestal, so that the rocker component is mounted on the electronic component by the pressing structure, the rocker component and the electronic component are without affording the excessive pressure force to cause a damage and a deformation of the electronic component.

The breaker 1 is provided with a fixed contact 20, a movable piece 4 extending in a first direction (D1), a thermally actuated element 5, a case 7 accommodating the movable piece 4 and the thermally actuated element 5, and a terminal piece 2 which partially protrudes outside the case 7 and is to be electrically connected with an external circuit. The terminal piece 2 has a first portion 21 and a second portions 22 having different heights from a bottom surface of the case 7, a first bent portion (23a) bent in a first bending direction, and a second bent portion (23b) bent in a second bending direction opposite to the first bending direction. The first bent portion (23a) and the second bent portion (23b) extend in parallel with the first direction (D1).
