D-512(00) ENCLOSED FUSED DISCONNECT SWITCH ABSTRACT OF THE DISCLOSURE 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 en- closure. 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.
