a 220 switch


A switch that controls a motor needs to be rated for both the HP of the motor as well as the voltage it operates at.

There is no code requirement for a control switch to open all hots, but it's generally a good idea to use a two pole switch to control a 240 volt motor. A two pole switch will have 4 terminals, a single pole has 2. A two pole switch breaks both hots, a single pole breaks only one.

But it's important to note that not all 4-terminal switches are double pole switches. Some are 4-way switches, and they look pretty much identical.

This is true, I was thinking of a basic toggle switch that mounts in a round hole, but light switches do indeed come in both versions.

Also, a lot of light switches don't have the HP rating stamped on them, you have to look in the manufacturers specbook.

They look alike but a 2 pole switch will say "on" and "off" if it is a toggle switch.
