Reviews

This product is not suitable for pitot pressure switch. Item was bench tested and adjusted to switch at 60 Kts. I came back to the bench later and the switch had closed without pressure applied. On further testing, the same result occurred repeatedly.

Product information didnt advise hose size and packaging didnt provide instructions as to use. I must have picked the correct pressure port because it works as expected.
