Hello Netters, I have a small problem and I am looking for a solution. I basically have 4 input lines:1,2,3,4 (with varying voltages). I also have a switch that can be either on or off. If the switch is on, say M is connected to R. If it is off then M would be connected to S. I am expecting four outputs: A,B,C,D. The results are tabulated in what follows. Switch Switch Input Output Off On 1 --- --- A 1 2 2 --- --- B 2 1 3 --- --- C 3 4 4 --- --- D 4 3 Switch R-- M ---- S-- Any ideas on how to accomplish this? The major requirement, I guess, would be to use only that switch. *** Michel Maksoud.
