Well, in that case you can arrange it so that *none* of them is real,
fooling him into wasting his time on them while failing to notice the
truly obfuscated *real* switch that you've hidden and that looks like
something else. Like maybe setting the fan speed to the third out of
four available levels while pressing in the fifth station selector
button out of six on the radio.
