Reviews

I wish I would have seen the other reviewers comments before ordering this switch. I struggled for a whole day thinking this was a defective air pressure switch before placing a slight vacuum on it and it then closes. So this is NOT a pressure switch, but a VACUUM Switch. Caveat Emptor.

This switch is actually a VACUUM switch, normally open and adjustable according to suction required to CLOSE switch.
