Please define what you mean by "switching the neutral". I made one
assumption
about what you meant, then when I read the first reply, it was obvious
that
another assumption of something entirely different was possible. So what
you
are saying is ambiguous at this point.
Which of the following is correct?
1. The neutral is being switched along with (in the same mechanism with)
each of the hot wire(s). Is this switch a snap switch, fused
disconnect,
or a circuit breaker?
2. The neutral is being switched to some load while the hot wire(s)
is/are
not being switched.
3. Each of 2 switches of the 3-way variety selects between hot and
neutral
and their commons supply power to a load (usually a light).
