Electronic bistable valve

Hi,
I need a mechanical bistable valve that opens with high pressure air like 25psi and after openning send a signal or current to a circuit...
how can I do that?

theres you answers there there after you need a schematic using mcu to detect open close signals

Or this page

Or search google using this criteria
25 psi valves with electronic open close output signalling

If you apply your knowledge laterally then think about the pressure switch on a washing machine or dishwasher "Except the wife of course which is normally but not always failsafe and sometimes temporary on occasions very explosve and quite dangerous in relation to man made units " You would arrive at the answers

Typically it can be surmised that most dishwashers don’t throw plates at you how ever the female human species does rather have this tendency particularly if the pressure switch fails In which case they may require a service if permissable else possibly consider a direct rather more boutique newer model as direct replacement

Mark, just let me see if I have correctly understood your problem:

Your occasionally very explosive temporary wife cannot be serviced, is dangerous to man-made units due to the lack of a failsafe pressure switch, and therefore you require a new boutique model as a direct replacement ?

Joking Frank lol Just me trying to add some humour in this miserable world

Yes, I suspected that, so I was trying to roll with it !-)

Post up a picture of your new boutique model when she arrives.

(No no no, just a portrait will be fine !)

They dont answer back which is really cool and you dont have to worry about the normal 2 weeks a month story ho hum !! and if they need reprogramming its just a simple change of code lol If they get too much just simply point the remote and instant silence "AaaaaaaH peace at last !! " lol
