Europa-List: Stall Warner - switch problems

I have the 0.072 PSI/5mBar/500Pascal Vacuum stall warner switch supplied by 
Europa
fitted in G-YETI (RS Components part No 317-443) but I'm struggling to get
it to work correctly - despite changing the switch for a new one today.  

The first switch would not reliably make contact at the stall warn speed 
(light/intermittent
squeaks at varying speeds) and whilst the other does work more reliably
it is closed/the horn sounds once the a/c is back on the ground/at zero
to low forward speed.  

Has anyone else had this problem and can share how they fixed it or can anyone
recommend another more reliable switch (based on personal experience in use) 
please?
The pipe between switch and the hole just below the wing leading edge
is correctly connected to the NO port A btw.

All inputs appreciated

Clive S
