ABSTRACT:
A method and apparatus for assembling an armature subassembly to a relay subassembly which includes (a) positioning the armature subassembly so the proximal end of the contactor is adjacent the upper wall of the relay frame and the armature is adjacent the front edge of the frame; (b) mechanically moving and holding the distal end of the contactor blade against the relay subassembly so that the armature is flush against the front edge of the frame; (c) mechanically moving and holding the proximal end of the contactor blade against the upper wall of the frame without inducing lateral movement or stress in the contactor blade; (d) relieving position-affecting stress on the contactor blade; (e) releasing the distal end of the contactor blade to assume a rest position so that the armature and front edge forms a gap; and (f) welding the proximal end of the contactor to the frame wall.
