Abstract

1473350 Mechanical switches PLESSEY CO Ltd 26 Feb 1975 [11 June 1974] 25863/74 Heading H1N A protective cover 1 for electrical switches 10 includes two columns of resilient arms 2 each of which is integral with the cover 1 at a fixed end and each of which has a push button 5 at a free end for operating an associated switch 10. As described, a plastics cover 1 is provided with two rows of integral arms 2, the free end of each of which has an integral or separately mounted (Figs. 3 and 4, not shown) push button 5 for operating a microswitch 10 which enables a telephone call to be made to a distant station. The cover 1 is provided with steps 6 defining a channel in which a tray (14) (Figs. 5 and 6, not shown) is slidable between a first position in which it is clear of a hole 7 receiving an actuator of a change-over switch and a second position in which it depresses the actuator. A sheet of paper (18) bearing the names of the parties served by the distant stations is secured to the tray (14). A first set of names aligned with the push buttons 5 is visible through windows (20) in a plate (19) fitted over the cover 1 and a second set of names is visible through the windows (20) when the tray (14) is in its second position.
