Europa-List: Stall Warner Switch

[Troy Maynor <wingnut54@charter.net>]

Hey Folks,
Can someone who has one, tell me at what airspeed the switch for the 
factory stall warner closes and at what speed it opens?  Is it a 
definite open and close or is it a variable arrangement? I am not happy 
with the one I have for a gear warning circuit. The dead band is too 
great and not the ideal airspeed anyway. Any information on the switch 
would be helpful too, like the hose fitting size, electrical 
connections, mounting, COST, etc.
