Abstract

A feedback system is disclosed for use in a remote control linear actuator device including a pair of actuator members that are relatively linearly displaceable by a motor, which feedback system includes a mounting bracket connected with one of the actuator members, a slide bar connected with the mounting bracket for linear movement by the other actuator member in a direction parallel with the direction of relative movement of said actuator members, and a rotary member operable by the slide bar to supply a feedback signal to the motor that is a function of the relative positions of the actuator members.
