Tnx for the circuit, I made one. Just ignore dennishryan68. I am intigrating it into a raspberry pi project

man u need to revamp your heading............... who in the hell want's to use a f switch...............duh..........

wait so i would have to keep switching the switch unless i got an electroonic switch
