<p>A binary encoding switch is described having a slide which is manually movable along a linear path adjacent a printed circuit board. The printed circuit board has five tracks comprised of conductive and non-conductive segments and a sixth track that is continuously conductive. The slide houses six conductive balls, each of which is biased into engagement with one of the tracks by a separate conductive leaf spring. A guide way is associated with the printed circuit board for guiding the slide along the linear path. A set of detents is also associated with the printed circuit board and a detent pin is carried by the slide. The detent pin is manually disengaged by the same operating tab used to move the slide longitudinally of the track. Electrical energy is continuously provided to the balls by way of the continuously conductive track and the leaf springs. Thus, the balls and tracks form individual switches which are open or closed in accordance with the conductive and non-conductive segments of the tracks. A diode associated with each of the five segmented tracks permits the conductive state of the respective ball and track switch to be used for binary coding purposes.</p> |
