A modular family of electrical switching relays that utilize interchangeable mechanical override knobs or blank fillers, combined with enclosures capable of containing two or more independently operable relays; where each independent operating relay can selectively be constructed to either have a mechanical override knob or to have a blank filler thus resulting in a broad number of product permutations from a minimum number of unique components that are required to build those permutations. An electromechanical relay with rotary manual on and off override control where the manual on and off control consists of three distinct positions for (1) forcing/maintaining the relay on, (2) forcing/maintaining the relay off, and (3) allowing the relay to automatically turn on and off or to be remotely turned on and off with an electrical signal. An electromechanical push/pull relay with manual on and off override control where the axis of rotation of the manual override control is perpendicular to the axis of relay push/pull direction.

Apparatus and method for latching one pole contact of at least one springy pole in a relay or hybrid switch for maintaining an engaging or disengaging state of at least one first contact with said pole contact by a mechanical latching device comprising a springy lock pin exerting minute force, a slider with indentation path for guiding the lock pin and a track for the slider, the latching device extends from an armature or the springy pole to a base or a body of the relay or the hybrid switch, said springy pole is guided by said slider movement propelled by one of a pull by a voltage rated magnetic coil fed by a pulse of said rated voltage and a push by a plunger, and for operating a stronger coil for switching higher electrical current the magnetic coil is fed with at least one discharge higher voltage to increase the magnetic pull power of the coil.

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.

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 mechanical switch (10) has a switching contact assembly (20), in particular a monostable, bistable or tristable switching contact assembly (20), and a base carrier (40), in which the switching contact assembly (20) is received The base carrier (40) has a holding device (50) for receiving an electromechanical actuator unit (100), which is designed in such a way that an electromechanical actuator unit (100) received in the holding device (50) can be supplied with voltage for effecting a state change of the switching contact assembly (20) independently of an external mechanical action on an operating mechanism by means of the electromechanical actuator unit (100).

A latching relay includes first and second coils and a common plunger operatively connected therebetween such that activation of the first coil moves the plunger in a first direction and activation of the second coil moves the plunger in a second direction, opposite the first direction, the first and second directions lying in a first plane. A limit switch includes a common contact and first and second coil contacts, where a position of the common contact is alternately switched between electrical connection to either the first or second coil contact based on a position of the plunger. A slide toggle accessible by a user is operatively connected to the plunger and slideable together with the plunger such that actuation of the slide toggle by the user causes manual actuation of the plunger. The slide toggle is slideable in a second plane parallel to the first plane.
