Abstract
A contactor includes a housing having a cavity with fixed contacts received in the cavity and a movable contact movable within the cavity to mate to the fixed contacts and unmate from the fixed contacts. The movable contact electrically connecting the fixed contacts in the mated position. A mating gap is formed between the movable contact and the fixed contacts when the movable contact is unmated from the fixed contacts. The contactor includes an actuator operably coupled to the movable contact to move the movable contact within the cavity relative to the fixed contacts. The actuator includes a primary coil assembly and a secondary coil assembly. The primary coil assembly is operable to move the movable contact. The secondary coil assembly is operable independently from the primary coil assembly to change a length of the mating gap.
