MAGNET OPERATED PROGRAM DEVICE

1,175,584. Moving magnet switches. ROBERT BOSCH G.m.b.H. 3 Feb., 1967 [4 Feb., 1966], No. 5262/67. Heading H1N. A programme device for rapidly setting a switch contact assembly comprises a plurality of magnetically operated, e.g. reed, switches 22 arranged in a pattern on a mounting-plate, the switch contacts being operable by individual permanent magnets 21 on a self locating non- magnetic programme card, the magnets being grouped in a plurality of separate units each containing a specific sub-programme. Pairs of switch contacts may be also operated selectively by coils 26 or be biased by additional permanent magnets 25. Each unit 22 may comprise an extruded strip on which the magnets are mounted, the strip having plugs (23, 24) of differing size for insertions in appropriately dimentioned apertures in the card. The magnets 21 are arranged so that the like poles are adjacent to each other. The magnets may be arranged in lines or obliquely, see Fig. 1 (not shown).
