Oscillation Switch
Maybe you want the oscillation mode on a footswitch...? Wire it as above
and your extra LED will light up when oscillation is engaged.
If you’re using DPDT (footswitch or toggle switch) just pretend that
middle row isn’t there.
You can use a footswitch daughterboard if you want to neatly mount the
LED for the oscillation. Connect the wires as below, but then flip the
PCB so the labels face down onto the footswitch so the LED pads are on
the correct side of the switch. You’ll also have to connect V to 9V and G
to ground to power the LED. Don’t forget the Current Limiting Resistor.
