If you disconnect the switch from the wires as I said, why would you need to
put a volt meter on it?

You can check a three-way switch with an ohm meter. Turn off the electric
and disconnect the switch from the wires. Normally there is one terminal
that's a different color than the other two terminals. Put one ohm meter
wire on the different color terminal and one on either of the two same

Never connect an ohmeter until you have first connected a voltmeter.
Even if you've turned the electric off, because eventually you will
skip turning it off for one reason or another. (A common reason is
that you forget. Or you've already turned it off and on a couple
times and you're tired of going to the basement. Or you lose track.
Or you will think you turned off the right breaker, but you'll get the
wrong one. )

Especially with 110 volts or more. With 9 volts, I don't think youll
burn out the ohmmeter, but you'll get into a bad habit.


colored terminals. Flip the switch, and the meter should change. Do this
for
the other same colored terminal. If the same thing happens, then the
switch
is ok.

3 way electrial wall switch question
The downstairs switch works as expected.
If the upstairs switch is then used to turn the
light off, the downstairs switch does not work.
Is the problem with the switch or is it wired wrong?
