Abstract

To decrease the number of switches and their connections to a speed control system, only two manually operated switches are provided to, respectively, allow for "engage", "disable" and "resume" operations, the system further including a bistable circuit which is connected to one of the manually operated switches to provide the manually operated switch with a dual function.
