Abstract
615,893. Electromagnetic switches. LANDIS & GYR SOC. ANON. April 17, 1945, No. 9573. Convention date, April 17, 1944. [Class 38 (v)] The armature 6 of an electromagnetic switch is secured to an insulating U-shaped lever 13 acting directly on springs 18, each carrying a plurality of contacts 19 co-operating with fixed contacts 10, 11 carried by cross-bars 7, 8. Each pair of fixed contacts is separated by an insulating barrier 9. The springs 18 are clamped at one end to a fixed cross-bar 24 and are actuated by a cross-bar 25 forming part of the lever 13. The lever 13 is carried by pivot pins 15 which may be integral with the centre limb of the lever or may be of metal, clamped by L- shaped members 26. A push-button 28 actuates contacts 30 to energize the magnet coil 5. Indication of switch position is provided at 23. The Specification as open to inspection under Sect. 91 describes a switch, Fig. 1 (Cancelled), wherein the springs 18 are mounted on the centre limb of the U-shaped lever 13, this limb being formed with barrier ridges 17 between springs, with one ridge extended to provide an actuating knob. This subjectmatter does not appear in the Specification as accepted.
