Maxon 19599 Switch 30067439-890 compatibility is determined by temperature

compatibility is determined by temperature rating and mounting

and relief valve discharge issues

Optimized 24V Coil: Designed for precise actuation and compatibility with standard HVAC control circuits

The normally open (N/O) pressure switch construction utilizes a high-sensitivity diaphragm to verify proper combustion air flow before allowing the ignition sequence to proceed

Technicians must ensure the air inlet holes face directly into the airflow for maximum sensitivity

Maxon 19599 Switch 30067439-890 compatibility is determined by temperatureThe Maxon 19599 is a high performance VOS 1 Valve Open Switch engineered for precise position indication on electro mechanical shut off valves. As a critical component in combustion safety circuits, this SPDT switch (Single Pole Double Throw) provides a reliable proof of open signal when the valve reaches its full open stroke. Designed for natural gas, propane, and fuel oil systems, it ensures seamless integration with flame safeguard controllers and
