ABSTRACT:
An electromagnetic relay 38 (FIG. 2) includes a cylindrical core 42 concentrically positioned within a coil assembly 40 and press fit into a frame 50, a resiliently mounted armature assembly 56, and electrical contacts 66,68, one mounted on the armature assembly 56 and one disposed in a fixed relationship to the frame 50. The coil assembly 40 is secured to the frame 50 by the use of extrusions 54 which precludes the need for a core head 24 and crush ribs 26 (FIG. 1). After assembling the relay 38, the core 42 is positioned by pressing the armature assembly 56 directly opposite the core 42 until the core 42 travels a predetermined distance beyond the electrical contact point for the contacts 66,68. This invention ensures precise positioning of the functional components and negates the accumulation of manufacturing tolerances in the relay 38.
