<p>A shorting switch (2) eliminates arcing faults in low voltage power distribution equipment (144). The switch includes a base (4) supporting a first side (6) and an opposite second side (8). A first end (12) of a spring (10) engages the first side (6) of the base (4). A first end (18) of a release bolt (16) engages the first side (6) of the base (4). An electrically activated, chemical charge (22) is disposed in an opening (24) of the release bolt (16) to fracture that bolt. A bridging contact (26) is biased by a second end (14) of the spring (10) toward the second side (8) of the base (4). A second end (20) of the release bolt (16) normally holds the bridging contact (26) and maintains the spring (10) in a compressed state. Two contacts (28, 30) are supported by the second side (8) of the base (4) for electrical engagement by the bridging contact (26) after fracture of the release bolt (16). Two terminals (32, 34) are respectively electrically connected to the two contacts (28, 30).</p> |
