Abstract
A multiposition controller includes a first switching element for switching on and off in accordance with a position of a movable object to be controlled and a second switching element for detecting the direction of movement of the object. The second switching element switches off when the object is positioned at one side from an initial position of the object, while it switches on when the object is positioned at the other side from the initial position of the object. Furthermore, the second switching element remains off or on when the object is positioned at the initial position. By such a simple structure, an accurate position control can be achieved.
