21st Century Fashion Kit: Inflation
Momentary Push Button
If you prefer to not make your own felt switch, using a standard push button will work just as well.
Solder the red voltage wires of the squirrel cage blower and the 9V snap connector together. Then solder the momentary push button switch between the white ground squirrel cage blower wire and the black ground 9V snap connector. Cover your soldered connections with electrical tape or heat shrink to cover any exposed wires and to avoid shorting!
