Abstract

1435252 Touch switches BROWN BOVERI & CIE AG 13 Feb 1974 [21 April 1973] 6573/74 Heading G1N [Also in Division H2] The invention relates to the construction of an electronic touch switch having a circuit arrangement of the kind disclosed in Specification 1435251. The touch-plate and monostable pulse circuit are mounted in a snap on cover for a flush-fitting wallbox housing the bi-stable trigger circuit and switching triac. Spring-load contacts in the cover make connection between the two parts. As shown Fig. 1 the trigger/switching unit is mounted on a board 3 above the suppressor choke 14 and the leads are brought to a screwed terminal block 4..7 (Another view of this unit is illustrated in Fig. 2 (not shown)). The unit is housed in an insulating box 16. The cover part 20 is preferably of red translucent material so that an indicator lamp (45) can shire through the sides and includes a metallic anodized aluminium touch-plate (37) and the monostable unit mounted on a circuit board 21. Contact springs 30..33 housed in bores in the cover, connect the monstable unit to the terminal screws 4..7 when the cover is in place. The cover is retained by spring clips 35 engaging slots in the top of the insulating box 16. (Other views of the top cover are illustrated in Figs. 5 and 6 (not shown)) The insulating box may be located in a conventional wall box (44) by lugs 19 forced outwardly by screws 19a.
