MAGNET AIDED SOLENOID FOR AN ELECTRICAL SWITCH

摘要

A solenoid (12) is provided for an electrical switch. The solenoid (12) includes a coil (50) having a passageway extending therethrough along a central longitudinal axis (96). The solenoid (12) also includes a movable core (46) having a coil segment (100) and a magnet segment (102). The coil segment (100) is received within the passageway of the coil (50) such that the coil (50) extends around the coil segment (100). The magnet segment (102) includes a radially outer surface (103) relative to the central longitudinal axis (96) of the passageway of the coil (50). The movable core (46) is movable relative to the coil (50) along the central longitudinal axis (96) such that the coil segment (100) is movable within the passageway of the coil (50) along the central longitudinal axis (96). A permanent magnet (54) extends around at least a portion of the radially outer surface (103) of the magnet segment (102) of the movable core (46). The movable core (46) is movable along the central longitudinal axis (96) relative to the permanent magnet (54).
