PROPORTIONAL SPEED CONTROL ARRANGEMENT ABSTRACT OF THE DISCLOSURE A proportional speed control arrangement (100) is disclosed for use with vehicles requiring variable velocities of operation. Specifically, the arrangement is utilized with a traction motor apparatus (101) to provide velocity adjustments to a service type of vehicle via electronic circuitry responsive to signals generated from an interface controller (102). The interface controller (102) comprises acceleration switches (KI, KD) and an enabling switch (KE) which are responsive to activation thereof by external means to establish velocity command signals. The velocity command signals control the application of energizing signals to the motor apparatus. A requisite velocity is maintained by deactivation of the acceleration switches while correspondingly maintaining activation of the enabling switch.
