With respect to Ric Argente's "squat" switch -- actually an airspeed switch 
rather than a weight on wheels switch -- I have a comment and a question.

A fellow Lancair builder in Lompoc CA had a bypass switch behind the 
instrument panel so that he could defeat the airspeed switch for ground maintenance of 
the gear system.  He did not intend for this bypass switch to be accessible 
in flight.  He had one of those red switch guards over it that automatically 
flips the bypass switch when the cover is down.  It's hard to notice a switch in 
the wrong positrion but easy to see when a switch guard is flipped up.  I 
though that was a good idea and intend to install mine that way this winter.

As for the question, I assume that the airspeed switch is normally open 
unless pressure is applied, and the "landing gear down" signal goes from the 
landing gear switch through this pressure switch and thence to the landing gear up 
relay.  (Or from the pressure switch to the gear handle to the relay -- it 
doesn't matter).  Is this how all y'all are wiring it up?

LNC2 70%

p.s.  I installed the horizontal and vertical tails this past week during a 
one-week vacation with the aid of a gullible friend.  Also, the bottom of the 
fuselage and wings are now filled and primed.  So I'm saying that my project is 
70% complete.  Two weeks ago I was saying 51%.  (Gee, 19% progress in two 
weeks.  Sounds almost like a Legacy, doesn't it?)  High time, too -- we noticed 
that my vertical fin parts on my "Super Fast Build" 360 were made in the 
Philippines 10 years ago this month.  It now looks like a real airplane.  Walking 
into the garage is pretty cool....
