First, a 7809 requires at least 3 Volt higher input voltage
Second, two capacitors are needed, one at the input of ~ 330nF and the output ~ 100nF (see specs 7809)

Why not like this ?
In off position you can charger the batterie without power concumption from the batterie.
In on postion you can use the 5Volt USB and the 9Volt barrel to feed the shell.
Release the USB in off position and there is no power at all to the shell.
