Abstract

1,110,815. Retractive switches. HERBERT, B.S.A. ELECTRICS Ltd. 25 Nov., 1964, [6 Dec., 1963], No. 48264/63. Heading H1N. A limit switch replacement unit comprises a hollow housing part 2, containing an operating mechanism and a pivoted movable contactcarrier arm 19, the mechanism including a switch-actuating shaft 13, operating lever 14 and actuating arm 22. The snap-acting mechanism is more fully described in Specifications 1,110,816 and 1,110,817. Housing part 1 is permanently attached to a machine, for example by screws through holes 3, 4, and housing part 2 is replaceably attached to part 1 by screws 9, and located relative thereto by bosses 11. Pivoted arm 19 insulatingly carries a movable contact bar 21 which bridges contacts 7, 7a, in one end position and contacts (8), (8 a ), in its other end position (Fig. 3, not shown). During transport a replacement unit is protected by a transparent insulating cap, similar in shape housing part 1.
