ABSTRACT:
Harsh full voltage conductive switching action is removed from a commutator-type rotary switch integral with a motor assembly and is placed in relay contacts external to the motor assembly by controlling reduced current through the rotary switch to the relay to maintain the relay energized after a control voltage is removed from the relay, and initiating a fixed time one-shot pulse generator in response to the rotary switch opening the reduced current to de-energize the relay and switch the load into a dynamic braking circuit at a particularly timed moment.
