The motor speed control has a bistable device to start and stop the machine in response to signals from a switch and an extreme lower speed control to drive the motor at an extreme low speed in response to a signal from a switch. Motor speed control also has counters which when set and actuated by a switch execute a predetermined finite number of stitches. Motor control device also has circuits allowing the motor to operate in response to a variable speed control switch.
