Abstract
An air circuit breaker movable contact arm assembly is presented. The movable contact arm assembly comprises an electrically-conductive support having at least one slot formed therein to receive a first end of the movable contact arm. The movable contact arm comprises first and second sides which face side walls of the electrically-conductive support within the slot. A spring washer is disposed at the first end of the movable contact arm and loads the second side of the movable contact arm against one side wall of the electrically-conductive support to form a variably conducting joint therebetween. By using a spring washer, the movable contact arm pivotally engages the other facing side wall of the electrically-conductive support to provide a variable pivot point. The variable pivot point of the contact arm assembly permits an additional degree of freedom allowing the movable contact arm to rotate about a separate, variable pivot point.
