ABSTRACT:
A structure for mounting an armature assembly to a frame of an electromagnetic relay is disclosed. Various construction details are developed which disclose a shaped bearing disposed on a frame and an armature assembly having a complementary bearing surface. The engagement of the shaped bearing and bearing surface permits pivoting of the armature assembly while providing capture of the armature assembly to the frame. In one embodiment, an electromagnetic relay (70) includes a frame (72) having a pair of spherical bearings (88, 90) and an armature assembly (78) having a pair of spherical recesses (102, 104) formed and positioned to complement the spherical bearings.
