Hi there,
I am going to make an ABC|XYZ switch, I already understand how to wire everything, but I am a little stumped on the LEDs.
I've read that you need to use a resistor for each LED in a parallel circuit. However I feel this situation may be slightly different. The device is going to use two 4P3T rotary switches to select input and output devices, with 3 Poles being for Left Right and Ground, and the fourth pole being for the LEDs. To me it seems that the poles are in parallel, and therefore I would only need a resistor for each switch as opposed to each LED.
So will this work fine? Or am I going to burn out my LEDs?
