Sliding contact control switch pad |
摘要 |
A controller is provided which includes a plurality of equally spaced sensors disposed symmetrically about an intersection of at least two orthogonal axes and spaced from such axes by a null zone which is concentric with such sensors. Control circuitry is electrically connected to the sensors to control movement of a controlled object in a direction which is related to the position of an operator's finger and the like relative to such intersection.
