Bruce,
Thanks for the link to the pressure switches. I’m
looking at airspeed pressure switch options for possibly toggling in lower trim
tab servo speeds at higher air speeds. I did a quick spreadsheet to see
if the pressures for the switches at the link were in the needed range.
If I did the calculations right, it looks like the lowest airspeed for the
lowest pressure switch at that link (7.5-145 psi range) is for 100 kts.
Tom,
I can point you toward this 55 to 140 kts range airpseed switch
offered by TCW Technologies – they make the Safety Trim product: http://www.tcwtech.com/usw-1.HTM
You get the switch and relay for $95.
Hope this helps. Good luck,

This is what I use for up/down pressure control on my
GIII. It's an adjustable solid state pressure switch. Last one on the page.

Subject: [LML] Low Pressure Gear Switch Needed
I am helping with a new prototype that has a gear system
similar to a
LNC2 or Legacy. We are trying to get it flying
so we can make Oshkosh
this year. We recently ran into a bit of a
holdup. The PS550 low
pressure switch for the landing gear system is on back
order with
Lancair for at least 1 month. This would not leave
us enough time to
test the gear system before the show. Does anybody
know of an alternate
source for this pressure switch? Or, anybody have
an extra to sell?
Rent? Loan for a month? :)
Thanks for your help.
