ABSTRACT:
In an electrically controlled shift actuator (110, 120, 130) and a control system (140) therefor of the type utilizing a cam or scotch yoke flywheel adapted to move a shift member (28, 96) to a preselected one of at least two spaced-apart shift positions. In one embodiment the shift member is in a preloaded condition provided by coiled spring (84) associated with the actuator. The control system employs a circuit having a control switch (100), a first switch (108), and a second switch (112) interconnectable in such a manner that a cam (70) responsive to the rotational position of the motor is able to change the condition of the first and second switching in a prescribed manner to move the shift member. The control system preferably includes energy dissipating resistor (120) for dynamically braking the motor and speed indicator (124) when the actuator is used as a shift actuator for a vehicle.
