ABSTRACT:
An enclosed multipole fuse disconnect switch is constructed of a single molded base, a single contact carrier, and an overcenter spring powered toggle mechanism constructed solely of a coiled compression spring and a stamped sheet metal tongue which extends through an aperture in the contact carrier. The tongue is formed integrally with a pivot shaft through which operating forces are applied to the toggle mechanism. Each pole includes a U-shaped bridging contact constructed of spring metal and floatingly mounted in an aperture of the contact carrier.
One end of the pivot shaft extends into a slot in the enlarged end of a bearing rivet that extends through the sidewall of the switch enclosure and is keyed to a manual operating member at one end thereof. The latter extends through a guide slot in an arcuate bracket outside the enclosure. With the operating member in switch open position, an aperture in the member is aligned with an aperture in the bracket to receive a padlock for maintaining the operating member in switch open position.
