Abstract

276,686. Weber, E. Aug. 26, 1926, [Convention date]. Plug couplings combined with electric switches. A rotary milled switchoperating member 4 projects through a rectangular slot in the cover 2, the member 4 being mounted loosely upon the rotary switch shaft 3. A spiral spring 11 is interposed between the member 11 and the shaft 3, the amount of lost motion during switch operation being limited by a projection 12 of the shaft working in a segmental slot 13 in the operating member (Fig. 4). The shaft 3 carries two pairs of diametrically-interconnected insulated contact plates 14 bridging pairs of fixed contacts 9 twice during a revolution spring blade 5 engaging the square side 3<1> of the shaft to hold the switch in its on or off position. The shaft 3 is journaled in plates 6 held in recesses of the insulating base 1. The switch base is fitted with plug sockets 8 one of which is joined electrically to a pair of the fixed contacts 9.
