Abstract
There is provided a mechanism for engaging a power takeoff employed primarily to drive a load from a truck engine having a solenoid with a high energy coil that is energized for a short interval to produce engagement of the power takeoff and a low energy coil to maintain engagement of the power takeoff. The mechanism includes an armature movable from a retracted to an activated position to move the power takeoff engagement mechanism to a power takeoff engaged position and a high rate spring which is compressed if the power takeoff does not engage whereby to return the armature to its retracted position upon de-energization of the high energy coil. A second lower rate spring moves the armature to its retracted position upon de-energization of the lower energy coil.
