Abstract

900,328. Indicators for switches; handactuating devices for switches; switch cases. NORTHERN ORDNANCE Inc. Dec. 5, 1960 [Sept. 21, 1960], No. 41818/60. Class 38 (5). An indicating push-button for operating an assemby of micro-switches 44 comprises a longitudinally sectionized plunger 82 of lighttransmitting material, such as polymerized methyl methacrylate, slidable in a tubular housing 22 which is secured to a panel P by means of a lock-nut 106. A flexible transparent plastic cover 110 is moulded to the locknut 106, which also carries a gasket 112, thus rendering the assembly moisture - proof. Switches 44 are carried in a bracket 16 adjustably mounted on the end of housing 22 by means of a threaded ferrule 18 which guides an actuating button 36. When plunger 82 is depressed against spring 116 it presses button 36 which operates snap-acting plates 40, 42 to actuate the switches 44. Plunger 82 comprises two semi-cylindrical portions 86 and 88 cemented together with a light-reflecting opaque plate 90 therebetween and a translucent disc 94 at the top. An opaque reflective coating 102 is applied to the outside of the plunger 82. Each portion 86 and 88 has a slot 92 therein to accommodate the tips of respective lamps 62 mounted on housing 22, as shown. Lamps 62 may be used for separate indications or In parallel for filament failure display.
