| An electric switching device for fast closing of a high current comprises one movable contact element (4) and one fixed contact element (5), which form a sliding contact. A spring member (2) operates the first contact element (4). During the closing movement, the first contact element completes an acceleration phase (t1), during which the spring force stored in the spring member (2) by clamping is transformed into kinetic energy of the movable contact element. Then follows a movement phase (t2-t1), during which the movable contact element moves towards the closed position at constant speed. The spring member (2) comprises a freely journalled torsion-spring rod, one end of which is fixed to an operating arm (3) which is freely rotatable between a first support (7) and a second support (8). The contact element (4) is fixed to the second end of the torsion-spring rod, the torsion-spring rod being clamped by rotating the contact element in the opening direction with the operating arm against the first support. The fixed contact element (5) comprises a plurality of contact fingers (14) as well as a plurality of spring fingers (17). The contact fingers are made of a first electrically conducting material with good electrical conductivity. The spring fingers (17) are made of a second conducting material with a high yield point and designed so as to have an essentially higher resonance frequency than the contact fingers. The spring fingers are adapted to rapidly resume a contact position after a deflection excited transversely of the closing direction. | ||||||

The present invention is a cell bypass switch (2) particularly designed for aerospace applications. The cell bypass switch can sense a battery cell failure and automatically opens an alternate path around the failed cell, bypassing the failure and allowing the remainder of the battery system to continue its function. The cell bypass switch is designed to be placed in parallel with the battery cell it protects. The present invention includes two electro-mechanical actuator assemblies which are mounted on the top end of the housing for operating two plungers (36) respectively. Each of the electro-mechanical actuator assembly includes two spool halves (42,44) which are held together by a tight winding of a restraining wire (46) that terminates in a bridge wire (47) connecting two electrical terminals of the electro-mechanical actuator. Each spool, by virtue of the restraining wire winding, can restrain a spring loaded plunger. However, when sufficient electrical current is passed through the terminals and the bridge wire, the bridge wire will heat up and break under the applied tension load. This causes the restraining wire to unwind, separating the spool halves and releasing the plunger. |
