Air Touch Linear Pneumatic Hand Control by Wells-Engberg. This Air Touch Linear Pneumatic hand control is designed for vehicles equipped with power steering, power brakes
and automatic transmissions .Instead of a joystick moving in an arc, the linear joystick moves straight line push forward for brake and pull straight back for acceleration. This allows better feedback and more precise control with less air consumption. Since the cylinders attach behind the dash and to the pedal arms, there are no bulky boxes or linkages to interfere with wheelchairs or able-bodied drivers.
