ABSTRACT:
The present invention teaches a control input device particularly suited to a number of applications on a motor vehicle. The device can be activated by the foot of an operator to transmit an electrical output signal which is a function of load or displacement. Such control input device includes a leaf spring mounted such that it can be bent in response to an application of a foot force. Attached to the leaf spring is a sensor which measures the bowing of the leaf spring and transmits a corresponding electrical output signal.
