Apparatus and method for latching one pole contact of at least one springy pole in one of a relay and an hybrid switch for maintaining one of engaging and 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 combination with at least one discharge higher voltage to increase the magnetic pull power of the coil.
