ABSTRACT:
A movable arm assembly for a circuit breaker includes a unitary structure having two blade portions being connected by a bend location. The bend location forms a gapless surface region. A contact is connected to the unitary structure wherein the gapless surface region and a contact surface of the contact are connected to form a joint therebetween. A method for forming a movable arm assembly includes forming a blank from a conductive sheet, the blank including a unitary structure having two blade portions, bending the blade portion at a bend location to form a gapless surface region at the bend location and joining a contact to the unitary structure on the gapless surface region at the bend location to form a movable arm assembly.
