Abstract

Method and apparatus for a mechanical latching of at least one pole of an hybrid switch selected from SPST, SPDT, DPDT, reversing DPDT, multi pole MPST and MPDT including the integration of one of a single and plurality of hybrid SPDT or DPDT switches using springy element to maintain the engagement between the poles and one of the contacts including PCB assembly, for operating electrical loads via the switch manual key including the introduction of a key-plunger combination into the latching hybrid switch and remotely by powering the coil by a power pulse, including a CPU program for providing any of the manual keys of each SPDT or DPDT connected in a traveler lines to the integrated switch-relay to switch on-off group of loads and all the loads of home automation network or grid via optical cable, RF, IR in line of sight and bus line.

Dependent claims

A latching hybrid switch comprising a spring driven latching device for maintaining an engaged state of at least one first contact with one of single throw and dual throw contact of at least one springy element pole, said latching device extended between said at least one pole and one of a base and a body of said hybrid switch comprising a lock link, a bar with indentation path for guiding said lock link and a receptacle for switching over the latching state from latch to release and from release to latch by compression;

said hybrid switch further comprising a magnetic coil, an armature and connection terminals for connecting power and at least one of a load and traveler lines and combinations thereof, said armature is actuated for a given time duration by at least one of a pull by said magnetic coil fed with an electric power pulse and a push by one of a plunger attached to and driven by a manual key for reversing said hybrid switch state;
said pole is one of attached to and actuated by said armature via said at least one of said pull and said push to simultaneously compress said latching device, each fresh said compress reverses the hybrid switch state by one of engaging and disengaging said single throw contact with said at least one first contact and by one of switching over the engagement of said dual throw contact between said at least one first contact and at least one second contact;
at least one of said pole and one of said first and second contact is one of structured to be said springy element comprising one of a spring and springy structure to provide said armature with a partial release when said given time duration is over and said pole is latched for enabling the releasing from said latching state by fresh compression for switching over said hybrid switch state with each fresh compress.

A method for latching at least one springy element pole with one of single throw and dual throw pole contact of a hybrid switch for maintaining an engaged state of at least one first contact with said pole contact by a spring driven latching device extended between said at least one pole and one of a base and a body of said hybrid switch comprising a lock link, a bar with indentation path for guiding said lock link and a receptacle, said pole is one of attached to and actuated by an armature, said armature is actuated for a given time duration by at least one of a pull by a magnetic coil of said hybrid switch fed with electric power pulse and a push by one of a plunger attached to and driven by a manual key for reversing said hybrid switch state and for compressing said latching device for one of latching and releasing said at least one pole;

each fresh compression of said latching device by said actuated armature reverses the hybrid switch state by one of engaging and disengaging said single throw pole contact with said at least one first contact and by one of switching over the engagement of said dual throw pole contact between said at least one first contact and at least one second contact, at least one of said pole contact and one of said first contact and second contact is one of structured onto said springy element comprising one of a spring and a springy structure for providing said armature with a partial release when said given time duration is over and said pole is latched, said method comprising the steps of:
a. actuating said armature by one of said pull and said push;
b. engaging said at least one pole with said at least one first contact for latching said at least one pole by said latching device;
c. maintaining said latching through and after said time duration;
d. releasing partially said armature when said time duration is over;
e. repeating said actuating for reversing said hybrid switch state selected from a group comprising from on to off, off to on, switch over, cross to straight and straight to cross.
