Abstract

1327904 Magnetic switches; switch cases HATTORI TOKEITEN KK 21 Sept 1971 [22 Sept 1970] 43966/71 Heading H1N A switch cover 17 has a plurality of resilient hooks 22 which are a friction fit in holes 26 in a supporting plate 24 and are a snap fit about the edge of a flange 14 of a switch case 1. The holes 26 are circular in cross-section whilst the hooks 22 are square in cross-section. A permanent magnet 4 and magnetic backing plate 5 are mounted on a push key 3 to actuate a sealed magnetic reed contact device 9. A return spring 20 acts between a lug 6 of backing plate 5 and a hook 19 of the cover 17. The contact device 13 is seated on cushion material 13 in the switch case. The reed terminals are connected to a printed circuit board.
