Abstract
248,124. Tucker, J. B. Dec. 17, 1924. Bases; cases; contacts. - Relates to tumbler switches mounted on the underside of the cover of a terminal box and consists in means for securing the switch and for facilitating the connection of the contacts to the supply leads. As shown, the cover 2 has two inwardly-projecting hollow pillars 5 arranged diametrically on either side of the opening for the dolly of the switch. These pillars register with two externally screwthreaded sleeves 9 passing through the insulating base of the switch and serving by means of the nuts 11 to secure the bridge in position. Fixing screws 6 passing through the sleeves and' into the hollow pillars secure the switch to the cover. The fixed contacts are located on the front face of the insulating block and extend from that face towards the underside of the cover. The terminals for these contacts extend through the block and project beyond the rear face thereof so as to facilitate connection. As shown in the Figure, the terminals constitute plug coupling members 14 connected to the leads and pressed into socket members in connection with the contacts, as described in Specification 235,662.
