Slider – the added resistor between S4 & S5 is merely a CLR for the Rate indicator LED. I prefer it a bit less bright and the added CLR reduces the brightens of it.
I used separate CLRs for the Rate and On-Off LEDs. The on-board CLR on the 3PDT Wiring board is for the On-Off indicator and the added resistor between S4 & S5 is for the Rate LED.
I didn’t use a bi-color LED on the 3PDT Wiring Board – I just wanted an On-Off indicator. I did not work up a scheme for using 2 LEDs on the 3PDT Wiring board (one for On-Off and the other Rte indication. That would require a different bit of attention for such re-wiring.
