Abstract
20,900. Tucker, J. H. Sept. 8. [Cognate Application, 22,163/10.] Earthing parts of.-In tumbler switches the ordinary fittings are modified, without the use of extra attached parts, to provide means for earthing the metal parts of the switch that do not carry current. In one form, one of the ordinary fixing-screws is dispensed with, and in its place a hollow terminal 2, Fig. 1, is substituted to serve the part of a fixing-screw, and at the same time accommodate an earthed wire 5; or the bridge-piece 9 may be extended, as shown in Fig. 6, and the earthed wire secured in a hole 12. When the switch is mounted on a conducting-base, the bridge-piece is extended, as shown in Fig. 4, and the extension secured to the base by a screw in the hole 16.
