ABSTRACT:
Each of a pair of low voltage, residential type circuit breaker housings includes a molded case, a mating cover, a spring clip, and a conductive contact member. The clip, generally U-shaped, has a stiff outer leg with smoothly formed edges, a base, and an inner leg forming two flat springs joined by a flat leg coupled to the base. The flat leg is case supported to stabilize the base and outer leg. The member has an outer conductive leg so formed that when the clip's stiff outer leg's inner surface opposes a connecting surface thereof, and spaced therefrom, a bus bar blade is receivable. The contact member includes a step having a riser in one direction joining at a roundly formed right angle with one end of its leg (the roundly formed angle and smoothly formed edges serving as lead-in contours for a bus bar blade) and a tread along a second orthogonally oriented direction, which tread rests on one of the flat springs. The contact member includes a formed configuration having one portion coupled to the leg's other end and oriented parallel to the riser, a second portion coupled to the first portion extending in a third orthogonal direction but parallel to the riser, and a third portion coupled to and perpendicular to the second portion. The second portion has an aperture for receiving the other flat spring. A fixed contact can be housed on the second portion.
