This sip/puff actuator was developed from an original design from the Herefordshire Panel, the electrical circuits  and motor are exactly the same as the Herefordshire Panel Device. I modified the actuator to use a cam and lever after realising almost all of the older sewing machine pedals are identical. More modern machines pedals differ. Motor mount uses a torque reaction switch to stop motor then it reaches a limit stop, a hand button is provided to stop machine and cycle cam back to zero.
