Abstract

25,833. Holt, F. B., and Smith, H. Nov. 11. Contacts. - The movable member or contactarm of the switch is constructed of tubular metal which is pressed flat at the place where it moves between contact clips or jaws. The jaws may also be made of tubing, split and flattened at the end. In the knife-switch shown in Fig. 1, the tubular contact-arm 1, which is of copper or other good conductor, has one flattened end 5 hinged between contact-clips 2, and the other flattened end 6 adapted to pass into and out of contact with clips 3. Each clip is formed of a partly flattened tube and is attached to the panel 4 by a screw collar and nut upon the round part. In a switch-fuse, shown in Fig. 4, short pieces of tube 11, 12 with flattened contact-making parts 6, 5 are joined to the ends of a cartridge fuse 13, the structure constituting the main switch arm. An auxiliary contact-blade 21 pivoted on the main contactblade at 22 is held back by the friction of the clips during the opening movement and finally drawn out by a spring 23.
