Abstract

533,445. Magnetic switches ; sparking preventing in switches. AUTOMATIC CONTROL CORPORATION. Aug. 11, 1939, No. 23226. Convention date, Aug. 15, 1938. [Class 38 (v)] A. lead 33 is connected to a switch blade 34 carrying a contact plate 40, which is urged upwardly by a leaf spring 41 and co-operates in upper and lower positions, respectively, with fixed contacts 18, 19 and 22, 23. The former are mounted on the ends of a bifurcated bracket 15 secured to terminals 14, and the contacts 22, 23 are on a bracket 21 secured to terminals 20. An extension 35 of the switch blade carries a pair of spaced armatures 36, 37 which co-operate with forward extensions 28 of magnetic members 27 so to provide a snap action in both directions of movement. Members 27 are spaced away from the limbs of a U-shaped permanent magnet 26 embedded, with members 27, in a plastic substance. This magnet also serves to blow out any arcs formed between the separating contacts, for which purpose, the members 27 are formed with upstanding lugs 29 against the separation-points.
