Abstract

660,975. Electromagnetic switches. LANDIS & GYR. SOC. ANON. Oct. 31, 1949. [Nov. 17, 1948]. No. 27876/49. Class 38 (v). In a switch in which energization of a magnet 4 or 5 tilts an armature 7 into one or other of its extreme positions in which contacts 11, 13 or 12, 14 engage, a dead-centre S-shaped wire spring 17 maintaining the position, the armature 7 has a magnetic extension 8 which is bent at both ends to provide bearings for a pivot pin 6. The cores 2, 3 of the magnets have eccentricallypositioned reduced portions or necks providing recesses into which the armature enters and diminishes the magnetic attraction towards the end of the stroke. The contacts 11, 12 are mounted on a spring 9 riveted to the extension 8 together with a copper strip 10 which has an S-shaped portion leading to a terminal screw 16. An indicating vane may be provided at one or both ends of the armature. Specifications 552,112 and 564,351 are referred to.
