A flow switch is a mechanical switch which responds to the flow of air or water by switching on or off. It generally operates using a paddle which is opened by the force of air or water passing through it.
When the switch detects the flow of air or water it sends a signal to the PCB to start the combustion process. It can also act as a safety device and send a signal if the flow rate is too high or too low.
