A switching assembly for mounting on a pedal has a flat shaped switch actuator constrained to move with a single degree of freedom in a plane parallel to the pedal face. A pressure member at the front of the pedal receives a control force from an operator and as it moves toward the pedal face moves the switch actuator through a cam linkage. The cam linkage includes cam surface extending close to the periphery of the pressure member so that the cam action is effective irrespective of the area of the pressure member pressed by an operator. The switching assembly is effective in changing switch settings of a plurality of switches in a predetermined order as the pedal is pressed irrespective of the point of application of control force to the pressure member. |
