Hello all, can somebody suggest a good place to get an air pressure
switch to hook into the Pieto line of an aircraft which will then in
turn operate the hourmeter when the aircraft is flying.

I used a switch in the pitot line for exactly this purpose. Go to
"www.digikey.com" and search for "pressure switch". Determine what
speed you want the switch to come on at (I chose 40 mph) and then
determine what pressure will be created at that speed and choose the
appropriate switch. I don't remember which one I used.
