Abstract

1,224,093. Magnetic switches. MITSUBISHI DENKI K.K. 7 Aug., 1969 [7 Aug., 1968], No. 39527/69. Heading HlN. A movable magnet operated switch has a rotatable member 22 with a plurality of permanent magnets 24a, 24b, 24c, 24d mounted thereon on a circle about the rotational axis and arranged to influence the flexible magnetic contact reeds of a contact unit 26 and the polarities of the permanent magnets are such that the needs are influenced either by magnetic poles of different polarities so that the contacts close or by magnetic poles of the same polarity so that the contacts open. The rotatable member 22 is a magnetic plate on a shaft 20 with an index dial 18 and the shaft 20 is driven in steps by a pawl 16 each time an electromagnet 10, 12, attracts its armature 14. The magnets 24a, 24b, 24c, 24d are polarized in a direction normal to the face of the member 22 to which they are attached the symbols N, S in Fig. 3 indicating the polarity of the pole faces adjacent the member 22.
