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.

The relay according to an embodiment of the disclosure includes a main body configured to open and close a circuit by an input signal, and a plurality of terminals extending from the main body and coupled to a PCB, wherein each of the plurality of terminals comprises an inclined extension portion configured to allow the main body to be spaced apart from the PCB and maintain an inclined state with respect to a surface of the PCB and a lower surface of the main body, and a coupling portion extending from the inclined extension portion in a direction to enter a coupling slot of the PCB.

An electric switch of the normally open type includes a body made of insulating material, an actuator that is moveable between a high rest position and a low active contact position, a first elastically deformable contact blade supported by the body, and a second elastically deformable contact blade supported by the body.
