1. A device for switching an electrical circuit, the device comprising:

  • a housing;

    a magnet coil mounted to the housing, said magnet coil having a polarity which is changeable;

    an armature seated at said magnet coil for pivoting in response to changes in said polarity, said armature having a bottom;

    an armature arm having an upper end rigidly connected to said bottom of said armature, said armature arm extending away from said armature bottom in a downward direction, said armature arm having a lower end;

    a first connecting arm extending in a substantially horizontal direction, said first connection arm having a first end connected to said lower end of said armature arm for pivoting motion relative thereto, said first connecting arm having a second end;

    a first pivot lever having an upper end mounted to said housing for pivoting about a fixed first pivot point, said first pivot lever extending in a downward slanting direction away from said fixed pivot point, said first pivot lever having a lower end mounted to said second end of said first connecting arm for pivoting relative thereto;

    a first actuator arm having an upper end mounted to said second end of said first connection arm for pivoting relative thereto, said first actuator arm extending in a downward slanting direction away from said upper end thereof, said first actuator arm having a lower end; and

    a first contact element communicating with said lower end of said first actuator arm, whereby a change in polarity of said magnet coil causes said armature and said armature arm to pivot, said first connecting arm to sidewardly displace, said first pivot lever to pivot in a downward direction to assume a more vertical orientation, said first actuator arm to pivot to assume a more vertical orientation and to displace said lower end thereof in a downward direction and press down said first contact element.
