Abstract

917,375. Magnetic switches. GENERAL MOTORS CORPORATION. Sept. 15, 1961 [Sept. 16, 1960], No. 33151/61. Class 38 (5). A pressure-responsive switch comprises two permanent magnets 56, 58, mounted on a plunger pin 46 on opposite sides of a freely movable magnetic plate 60 carrying contacts 62, 64, movement of said magnets towards and away from said plate causing its contacts to engage and disengage fixed contacts 42, 44. The plate has diametrically opposed extensions (Fig. 3, not shown) sliding in slots in a easing 30 which together prevent rotation of the plate and limit its axial movement. In operation, when pressure is applied to a diaphragm 18 it moves a plunger 28, plunger pin 46 and the permanent magnets 56, 58 to the right against return-spring 82. The plate 60 moves with the magnet 58 until it is arrested by the abutment of its extensions with the ends of the recesses in the housing whereupon it is attracted towards the permanent magnet 56 with a snap-action, closing contacts 42, 62 and 44, 64.
