Air Blast Switch Utilizing A Standard 20x6x9 Mm Microswitch. To Activate This Device, You Must First Add A Rubber Membrane With A Diameter Of 30mm And A Thickness Of 0.9mm (such As One Cut From A Bicycle Inner Tube). Secure This Component By Gluing It Into Place Within The Ring, And Then Attach The Small Pressure Plate Directly Onto The Membrane To Prevent Wear. Next, Introduce A Hose Into The Upper Portion Of The Housing, Using A Hole With A Diameter Of 5-6 Mm (enlarging As Necessary). Secure The Housing In Place Using 3mm Screws And Nuts. Dependent On The Amount Of Air Being Forced Into The Switch, You May Need To Drill A Small Hole (practically Invisible) Into The Top Of The Housing To Prevent Overpressure From Building Up Inside. Due To Its Non-Airtight Design, This Device Can Only Be Used As A Surge Switch.
