Mechanical bistable valve that triggers circuit upon opening at 25psi air pressure

The discussion addresses the need for a mechanical bistable valve that activates at approximately 25 psi air pressure and provides an electrical signal or current output to trigger a circuit. Suggested solutions include using pressure switches similar to those found in household appliances like washing machines or dishwashers, which detect pressure changes and output electrical signals. References to specific valve products and datasheets are provided, such as the PTV-139 valve from ppp.aero and technical documentation from Samson (t83500en.pdf), which may offer valves with electronic open/close output signaling suitable for the application. The use of a microcontroller (MCU) to interpret the valve's open/close signals and control the circuit is recommended. The discussion also includes humorous commentary unrelated to the technical topic.
