A contactor module is adapted to detect a switching state of a contactor. The contactor module includes a movable element that is arranged to transmit the movement of a switching element of the contactor to the contactor module; and a deflection lever attached to the movable element. The deflection lever is arranged to indicate the switching state.

Systems, devices, and methods including: a relay, the relay including: at least one contact; a reflector attached to at least one contact; a sensor, the sensor including: an emitter configured to emit a pulse; a detector configured to receive a portion of the emitted pulse; where the reflector may be configured to reflect at least a portion of the emitted pulse to be received by the detector when the at least one contact may be in at least one of: an open position and a closed position.

The present invention relates to a mechanical operating assembly for a bistable relay and a bistable relay assembly. The mechanical operating assembly comprises: an actuating mechanism mounted to a bracket, including an actuating member and a first transmitting member which is connected to a paddle, the actuating member is movable between an initial position in which the actuating member is not in contact with the first transmitting member and an actuating position, when the actuating member moves from the initial position to the actuating position, the actuating member contacts the first transmitting member; a reset mechanism mounted to the bracket, including a reset member and a second transmitting member which is in contact with the first transmitting member, the reset member is movable between an initial position and a reset position, the reset member contacts the second transmitting member when moving from the initial position to the reset position.

A switch assembly comprises a plurality of contacts, a switch including a contact bridge and an armature connected to the contact bridge, and a switch status detector positioned remotely and electrically isolated from the switch. The switch has an open position in which the contacts are electrically separated from one another and a closed position in which the contacts are in electrical contact with each other through the contact bridge. The switch status detector includes an electronic oscillator coupled with a coil wrapped around a core. The switch status detector outputs an oscillating voltage that varies depending upon a position of the switch between the open position and the closed position.

A state of a tripping solenoid in a circuit breaker is determined by a primary coil and a secondary coil wound around a hollow body of a solenoid. The secondary coil is positioned within magnetic coupling distance from the primary coil and is configured to produce a sensing voltage based on the primary coil voltage. A ferromagnetic plunger positioned in the hollow body, is configured to slide axially to a tripped position to trip the circuit breaker when a trip voltage is applied to the primary coil. A plunger position detecting circuit connected to the secondary coil, is configured to detect the position of the plunger in the hollow body of the solenoid based on the sensing voltage. A reduction or absence of the sensing voltage indicates a faulty or broken connection in the primary coil.
