ABSTRACT:
Electrically operable switching circuitry is effective to energize, in response to the application of a control signal, a commutated electrical motor in a first direction for driving a member driven thereby through a travel stroke and to energize, in response to the removal of the control signal, the motor in a second direction for driving the member driven thereby through another opposite travel stroke and an electrical signal produced while the motor is in the run mode is effective to maintain the switching circuitry operated for motor energization. Upon motor stall when the member driven thereby has reached the end of a travel stroke, the electrical signal produced while the motor is in the "Run" mode terminates and the switching circuitry then operates to deenergize the motor.
