An electrically driven lockable actuator for an airline seat assembly is provided with an extendable and retractable actuator arm driven through a gear train by an electric motor. The actuator arm can be locked or unlocked through the gear train to the electric motor by manual activation of a clutch mechanism. Regardless of whether the actuator arm is locked or unlocked, the position of the actuator arm is copied by a follower extending exterior to the actuator. The follower is adjustable to selectively activate limit switches to disconnect power to the driving motor. The switch arm is compact and mounted on the actuator so that electrical control of the motor relative to the operation of the lockable actuator is realized without reference to the nature of the design of the seat assembly.
