hey neil,
thanks for your reply
i had exactly the same idea, but, that would "tie" the inputs together whatever the switch position would be... say, (for a 4 position 3 pole rotary switch) in position 1 inputs of circuits 2,3 and 4 are grounded and in poistion 2, inputs 1, 3 and 4 are grounded but, even if not connected to ground, inputs 2,3 and 4 are still tied together and thus, every input is grounded all the time...
am I right?
