Abstract

A method of manufacturing a current switch magnetic intensifier that is constructed to be secured in generally close proximity to the stationary contact of the current switch. During termination of the communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with a stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. The intensifier is fitted proximate the stationary contact so that a pair of arc rails extend beyond the stationary contact such that a force of a magnetic field generated by the contactor magnetic intensified is directed in a common direction with a direction of reduced resistance of the pair of arc rails to ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor.
