Abstract
The invention relates to a manual control apparatus, such as a control pedal for a drive-by-wire control systems, and similar applications. According to an aspect of the invention, the manual control apparatus comprises a hysteresis mechanism that provides more precise and controllable hysteresis than previous mechanism. According to a further aspect of the invention, the manual control apparatus comprises an angular position sensor, and the angular position sensor may comprise abutments that reduce variation in the sensor. According to a still further aspect of the invention, the manual control apparatus comprises a stop pin that regulates the position of a rotatable member relative to the position sensor with less variation. The stop pin may also be used as a single fastener the holds the manual control apparatus together.
