ABSTRACT:
A high current cell-shorting switch is provided with removable bus bar tips having an enlarged beveled area of contact. A plurality of movable tapered bridge contacts are arranged along a main shaft such that upon rotation of the shaft a plurality of the bridge contacts are simultaneously driven into spanning contact with two of the bus bar tips. The main shaft is supported by pairs of split collars which can be easily separated thereby permitting removal of the main shaft and associated contacts. Upon separation, the switch contacts and bus bar tips may be easily removed for refurbishing or replacement.
