How does this work?
The air switch push button contains a membrane which, when the button is pushed increases the
air pressure in the air pipe which in turn activates a mechanism inside the switch.
The top terminal on the switch is a common live feed in and the other two are N/O and
N/C respectively which means it does not matter which terminal you use for the switching signal.
With the Typhoon 1 you are turning the fan motor on which gives a live feed to the flow switch
which in turn signals the relay to give fuel and sparks at the same time.
