I have tried it both ways and it doesn't seem to matter although manually I can fiddle with it a bit to get it to work sometimes.

Exactly true. It is AC square ways (although they are not really square). A simple multimeter on reads a DC current to make the needle move. It is rather slow to respond compared to the AC switching that is going on so it only averages the current out to zero. There is a great big resister in line with the meter to calibrate it for voltage but it is really current it measure. To get it to read AC they put a diode in series that blocks all the AC in one direction so the meter can read the average of the voltage going in the other direction.

As you point out the numbers only really work for AC sine waves and they are just numbers fudged to read correct based on the sine wave. They really measure average.

I recently bought some left/right switches. They have dynamic power transfer to guide the power only in the direction of the switch but I find it does not work too well. It is very finicky and I play with the switch position to get power where I want it and sometimes it just won't work well at all.

Are others seeing the problem? Or did I just get a batch of bad switches. If so what did you do to correct the problem?
