Abstract
643,057. Electromagnetic switches. GUARDIAN ELECTRIC MANUFACTURING CO. Feb. 18, 1948, No. 4754. Convention date, Dec. 26, 1939. [Class 38(v)] An electromagnetic relay comprises a coil 23 mounted on a core 24 extending from a U-shaped field piece 10, 11, an armature 16 pivoted at 14 on one leg 11 of the field piece and an insulating plate 26 secured to the upper end of the core and constituting a head for the coil and having one or more portions extending sideways beyond a side or sides of the armature and carrying relay contacts. In the form shown in Fig. 2 the plate 26 extends both sides and each side carries contact springs such as 29, 30 adapted to be separated when the armature is attracted by a cross-piece 32 on the armature. In a modification, Fig. 4, the insulating plate 35 extends one side only and there carries two rigid fixed contact strips 37, 38 provided with extensions 37a, 37b carrying fixed contacts at their ends between which moves a contact strip 39a carried by the armature.
