Electrical switching device
First Claim
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.

Abstract
A device (11a; 11b) for switching an electrical circuit has a contact element (15a; 15b) which closes or opens the circuit between a first and a second terminal (13a, 14a; 13b, 14b). One end of the contact element (15a; 15b) is connected to the first terminal in a conducting fashion (13a; 13b). The second free end of the contact element (15a; 15b) closes the circuit in a first end position and opens the circuit in a second end position. A switchable magnetic field, preferably one whose polarity can be changed, moves, by means of an actuator device, the contact element (15a; 15b) into one of its two end positions. The activating device comprises a toggle lever (23a; 23b) to move the free end of the contact element (15a; 15b) into at least one of its two end positions. The device allows the holding power and/or the seating pressure of the free end of the contact element to be increased in its closed end position.
