Abstract
777,731. Switch covers. BILL SWITCHGEAR. Ltd. Aug. 15, 1955 [Aug. 24, 1954], No. 24545/54. Class 38(5) In a switch of the kind in which the cover cannot be removed when the switch is "on", an operating. lever 1 projects through an aperture in a detachable cover 2 and is associated with a forwardly directed catch piece which overlaps part of the cover when in the "on" position. As shown a catch piece 6a forms part of a lousely mounted plate 6 moved by the lever. A legend-bearing plate 5 is also loosely mounted to move with the lever and the legend ("off"/"on") is read through apertures in the cover and plate 6. A further embodiment (shown by dotted lines) comprises a lip lb, integral with the lever, which overlaps the cover in the "on" position.
