ABSTRACT:
A foot-operated accelerator pedal (18) in a lift truck (10) commonly provides for control of forward (14) and reverse (16) direction as well as acceleration (12) of the truck (10). Directional control portions (22) (24) of the pedal (18) are mounted on and movable relative to the accelerator control portion (20) for actuating switches upon making direct contact with the switches which are mounted on or near the pedal (18). A solution is offered to the common problem of relatively short wear life associated with such direct contact switches. The solution includes a pedal (18) having accelerator (20) and directional control portions (22) (24) and switches (80F) (80R) which are actuated without the need for direct contact with their actuators (92).
