Abstract
In the manufacture of a circuit breaker comprising a cover having a snap action blade attached thereto, with a movable contact mounted on the snap action blade, the optimum position of the movable contact with respect to a preselected locus is first determined and the movable contact is adjusted to the optimum position prior to closure of the circuit breaker. The optimum position prevents frying of the circuit breaker during operation.
