VPS Series

Pneumatic Vacuum Switch

These switches are used to convert a vacuum signal into a pneumatic signal, e.g. for use with an Air Saving kit. The switch uses a vacuum actuated membrane to operate a pressure Air 3/2 way Valve. The level at which the pressure Air Valve will operate can be adjusted using the lockable screw. Two options of valve are available a normally closed version or a normally open version.
