Abstract

1,168,245. Magnetic and electromagnetic switches. EICHNER-ORGANISATION G.m.b.H. 24 Oct., 1966 [23 Oct., 1965], No. 47734/66. Heading H1N. A position indicator comprises a sealed magnetic contact device 21 secured in a cut-out 22 on a printed circuit board 10 and actuated by flux emanating from a magnetic member 25 carried by a movable member 24 when the magnetic member is adjacent the contact device. The magnetic member 25 may be a permanent magnet or simply a soft iron member fixed to the armature of an electromagnet as in Specification 1,168,244. A magnetic member 26 shields the contact device physically, electrically and magnetically. A plurality of printed circuit boards carrying contact devices may be mounted side by side on pins which pass through holes 13 and 14 in the boards.
