W3 adjustable vacuum switches allow a micro-switch commutation once a preset vacuum value is reached. The preset vacuum is found by adjusting the external screw located at the center of the instrument, rotating the screw clockwise to decrease and counter-clockwise to increase the value. Mechanical stops protect both the spring and the micro-switch from over pressurization. Type W3S: Select normally open or normally closed electrical contacts.
