Abstract
Abstract A motion responsive electrical control apparatus for emitting an electrical control signal incrementally variable in desired correlation to a path of given mechanical motion. The apparatus includes a rotatably regulated electrical controller for emitting signals correlated to the angular position setting of the controller regulator. A cam member pivotally mounted onto the regulator of the controller is arcuately biased into overlying engagement with a movable follower defining a motion path to which the apparatus is to respond. Presettably adjustable pitch members incrementally spaced along the path of follower motion effect desired incremental changes in cam pitch thereat affording corresponding change to the controller position setting.
