Abstract

3105. Simplex Conduits, Ltd., and Elliott, W. R. Feb. 9. H o l d e r s . - A switch adapter for controlling the connexion between mains and two electric lamps, so that one of the lamps may be connected to the mains or so that both may be connected either in series or parallel or both disconnected, consists of four fixed contacts a, b, c, d connected to the circuits as shown, and two bridge-pieces B, F mechanically connected but insulated from one another. The bridge-pieces are turned by a spindle H, which, when mounted in an adapter for fitting two lamps in a single lamp-socket, is operated by cords attached to arms outside the casing.
