Abstract

1,272,381. Position signalling. MITSUBISHI DENKI K.K. 6 Jan., 1970 [6 Jan., 1969], No. 609/70. Heading G4H. [Also in Division H1] A device for producing a signal indicative of the angular position of a shaft 20 or scale 18 forming the output of a counter, comprises five reed switches 261-26V equispaced round the circumference of a circle. Four pairs of magnets 24a-24h are arranged on a segment of a disc 22, attached to shaft 20. The positions of the magnets being so arranged that for each discrete position, i.e., 0-9 of scale 18, a different pair of switches is activated.
