An air pressure switch, also known as the pressure safeguard, acts as a safety mechanism that makes sure there is not a buildup of toxic gasses within the appliance. It ensures that, if the fan fails within the appliance, the combustion process cannot proceed.. The PCB (Printed circuit board) closely monitors the air pressure switch to make sure it is in full working order before the appliance is fired up, preventing the appliance from starting without one of its key safety devices. Air Pressure switches are not present in every type of heater but can be found in some examples. Popular air pressure switches fitted are manufactured by Ambirad.
