<p>An improved switch assembly for use with a materials handling truck includes a pair switches that are conveniently placed in a natural position for actuation by an operator while walking along side the truck. The pair of switches are so placed on each side of a steering control handle to prevent inadvertent actuation and therefore inadvertent operation of the truck. One of the pair is operated by the thumb (100) while the other (110) is positioned to be operated by the fingers as the operator grasps the handle. A control circuit responds to the operation of both switches on one side to move the truck forward at a predetermined speed. <IMAGE></p> |
