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.
Per supplier, the MPL-503 series is adjustable as long as there is a letter at the end of the part number, so the MPL-503E is adjustable. Specifically for 40-150 of water.
The MPL 503E Air Pressure Switch in normally open and activates at 42 knots.
No, this switch is not FAA Approved for use in certified aircraft.
This unit is wired as a standard switch with an input from an air source to activate/deactivate.
This product is an air pressure switch to power the Hobbs. Look at part 10-00813 or for water application look at part 10-00326.
