ABSTRACT:
A tactile feedback apparatus, such as for a rotary optoelectronic motion encoder switch, has a ball that successively engages indentations in the surface of a hub. The ball is biased against the hub in a direction at an angle to the perpendicular to the surface by an angled leaf spring. The indentations in the hub are sufficiently deep so that the ball does not contact the floor of any indentation. As the hub wears, the spring inwardly biases the ball to contact the hub at a progressively decreasing radius. Consequently, the useful life of the apparatus is extended, and performance does not significantly degrade during the useful life.
