Abstract
Trip solenoids are disclosed in which a permanent magnet is positioned exteriorly of the armature case. In one version, a rotary solenoid has a permanent magnet between a ball race plate and the case and has a magnetic force sufficient to hold the rotary solenoid in its actuated position when the power is removed from the solenoid coil. An axial version of the trip solenoid is also disclosed.
