Adjustable vacuum switch

Description

Vacuum set point range is -2.9 to – 11.9 psi (= -200 to -822 mbar). It is a single pole dual throw (SPDT) switch so it can be used as normally open (NO) or normally closed (NC). The port is 0,25″ (=6,35mm). Temperature range is 4 degrees to 65 degrees.

Dimensions can be found below:

It is rated for 15A at 250 VAC. It does not have specs for VDC. So if you want to be sure, using a relay in between the vacuum pump and this switch is needed. It will not be able to handle the vacuum pump current draw over longer periods of time.

Below you will find an example wiring diagram.
