Bill,

Lancair sells a high quality air pressure switch that = will do nicely…adjustable and all, BUT it is expensive. Tell them you want = the airspeed sensing switch used on the IV-P as part of the gear retraction lockout = system.

I suspect there are cheaper alternatives available, but = I’d check the reliability carefully…no point in installing a warning = system that won’t be used often, and then have it not work when you really = need it to…
