If you have a real need to make this modification you would be better using a spring loaded push button switch - push 'on', release 'off' - similar to the way the button for a doorbell works. Panel mounted bush button switches are readily available and not expensive.
You only need a single pole switch, ie one with only two connectors, and the power rating is not important. what you are switching will not over stress any available switch. The third switch up from the botttom on this page is the sort that would do very well. The page is from a UK supplier but you will find similar switches anywhere.
That link only takes you to the main switch page ! You need the second page, then it's third up.
