What kind of electrical switch can i buy to turn a speaker on/off?

Question

and how do i set it up

Answer 1

With speakers there is a little more than just on/off.  Most amplifiers don't like having a load switched off. Some computers will allow it mostly because they are very low power but large systems won't!  You really need a "Speaker Switch" which will load the system when the speaker is switched off.

You can find these at electronics stores, stereo stores, etc I think even at Radio Shack.  Don't even think of just a standard off/on switch unless you like costly repairs.

You can make one using a double throw, double pole switch with an 8 ohm resistors (large enough for the amp) but if you are asking this question its not the way to go!

Here are some examples of what is available.

Answer 2

just use a toggle switch. Just make sure you don't flip it on and off very quickly, and when you switch it back on try not to have the volume to loud.
