Apparatus and method for powering a coil of latching relays and hybrid switches

An hybrid switch comprising a manual push key for actuating a plunger and a rated voltage magnetic coil for pulling an armature for sliding a slider with an indentation path by one of said plunger actuated by said key and by said armature pulled by a pulse feed of said rated voltage to said magnetic coil, wherein the slid slider actuates said at least one springy pole and said indentation path guides a springy lock pin movements into one of alternating state from latch to release and from release to latch by each said slid, wherein said slider is supported by a track included in one of a base and a body of said relay, extending between said armature and said springy pole;

• said at least one springy pole maintains one of engaging and disengaging state of at least one first contact with a single throw pole contact and one of engaging dual throw pole contact with said at least one first contact and alternately engaging at least one second contact during each said slid and during each movement of said springy lock pin into one of said latch and release state respectively;
• said springy lock pin exerts minute guiding force onto said indentation path and said at least one springy pole reversely propels said slider when said one of feed and actuate is cut and guides the springy lock pin into one of a latch state via a partial release movement and into a full release state, enabling said engaging of said pole contact with said one of first and second contact by one of said manual push and magnetic pull commensurate with said rated voltage pulse needed to pull said armature, said sliding, said actuating at least one springy pole and said minute guiding force by said springy lock pin onto said indentation path.

A method for latching at least one of a single throw and dual throw pole contact of at least one springy pole included 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 springy pole contact, said springy pole is actuated by a slider with an indentation path for guiding a springy lock pin movements from one of release and partial release position to a maximum slid position by a short push of said slider and reversing the movements by the springy pressure of said springy pole from said maximum slid to one of said partial and full release position when said push is stopped;

• said short push via one of a plunger and an armature attracted by a magnetic coil fed with a short duration rated voltage pulse for exerting a pull force commensurate with applied forces needed to push said slider to said maximum slid position via a track extended to one of a base and a body of said one of a relay and hybrid switch, said method comprising the steps of:
• a. pushing said slider by exerting a push force through one of a manual push of said plunger and a feed of said short duration rated voltage pulse to said coil for generating a pull force commensurate with said forces for said attracted armature for sliding said slider to said maximum slid position with said lock pin passing said latch position;
• b. stopping said push for enabling the springy pole to propel the slider in reverse direction of a partial release movement for guiding the springy lock pin into said latch position of said slider and maintain said at least one of said engage and disengage of at least one first contact with said springy pole contact throughout all movements between said latching position and said maximum slid position;
• c. re-pushing said slider by exerting a push force through one of said feed and said manual push by one of a finger and a mechanical element respectively for sliding said slider to said maximum slid position directing said lock pin to a release area guided by structured ridges included in the indentation path;
• and
• d. stopping said push for reversing the state of and said engagement by said springy pole contact and propel the slider in reverse direction all the way guiding the lock pin into full release area, awaiting a fresh said pushing.
