Abstract

574,269. Retractive switches ; switch bases and covers. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. Aug. 29, 1942, No. 12202. [Class 38 (v)] A multiple switch housing 1 has a retractable plate 13, capable of depression against the pressure of a bared spring 13d to operate the switch. The operating arms 14 of two other retractable switches 7, 8 lie above the plate 13 at separated points. A pressure plate rests above these and is so mounted that either 7 or 8 or both can be operated by pressing on appropriate parts of the plate, and, on each occasion the plate 13 is also depressed to operate its switch. Switches 7, 8 are each in series with a switch 9 operable by a flap-plate which can be swung to cover the right hand part of the housing 1, in which position switches 7, 8 cannot be operated, and the overlying part of the pressure plate is covered. The left hand part is uncovered, pressure on which will operate switch 13 only by pressure on 13c.
