I want to do this.. but how?

[Yousef]

Proposition:
I want to press a button that will switch between my neck and bridge pickup.

Example:
I'm on bridge pickup, I press the button and it switched to neck pickup and stays there. When I press the button again it switches back to bridge pickup.

What I need:
Basically, when I press the button down, how do I keep it pressed without holding it? I did a kill switch mod and you have to keep the button held for it to be muted.. how do I make it so that when I press it down it stays off, then when I press it again it un-mutes? Is it a special type of push button? Or do I just have to wire it in a special way? The push button I'm using has 2 prongs on it.

Why?
I think it would be cool just to push a button instead of flicking the 5 way selector. Will be faster!!

Thanks.
