Abstract
A low voltage vacuum switch and operating mechanism is detailed which is readily used as a shorting switch arrangement in electrolytic cells between the high current carrying bus bars of the cell. The switch has a very low profile and axial contact travel distance and is opened and closed by a means which translates rotational motion to a generally axial contact movement via a cam and connecting member, with overtravel dished washer spring means provided to keep the contacts closed until a positive opening force is applied. The low voltage vacuum shorting switch is detailed with axially movable non-weld contacts. The switch has a compact, rugged design for use in low voltage, high current severe environment application. A pair of thin flexible annular members having annular corrugations formed therein permit axial movement of the contacts.
