Cliff – to clarify any ambiguity on the CLR question . . . . If the indicator LED is going to be on the 3PDT PCB, then the CLR on that 3PDT PCB must be used and neither the LED or CLR on the circuit board need be used. If the LED is going to be used on the circuit board, then the CLR on the circuit board must be used. The LED and CLR on the 3PDT PCB would be redundant when the circuit board is using the LED and CLR. The CLR must used on the same board as the LED resides. Hope that helps.
