Not sure I understand the question. The switch interupts the hot line side of the light. Hot to one side of switch, the other side of the switch to the light, with neutral and ground supplied to the light.

Perhaps the OP means a 3-way switch (light operated from 2 different switches)?
If so, search this site or google the term; it has been covered multiple times or post your particulars.

There are at least five different configurations that will work. It depends if the power is at the light or one of the swithces. It depends if the switches are one either side or one side of light etc. We need a lot more details.

Here are some of the options.

In Australia this is called a two way switch,
Any idea's why you call this a three way switch ?
To us a three way switch,
would have three switchs,
also possible,
with the correct type of switchs used.

I think the reason is that there are three possible switch position combinations: both up, both down, or one up and one down (which are equivalent). Thus, there are three "ways" the switches can be flipped.
