The pole of s1 is not attached at s4?

I forgot to attach S4 to the positive side of the circuit

Detail of the pwm circuit?
Ideally, if you can attach the resistors directly to the selector sw, that'd be the way to go.

I know but 4 relay are cheaper than a selector rated for that current

What current?
Far as I know, The feed back current thru those resistors shouldn't be significant.

I checked and there are about 3.6V, can I use this selector?

I post also the photos of the PWM control
