I would like to build a game buzz just like family feud on TV. I was thinking to use two big switches (emergency switch see the picture) with Christmas LED light at front of the table and the switch will be ontop table. just like Family Feud on TV. My concern that the big switch will work? Do I need to add little power on the switch or not?

Any switch will work, but don't you want to use a big "arcade button" instead of a "machine kill switch".

No doubt because the "machine kill switch" is twice the size of the "arcade button" and is exactly what is used in the actual game shows.
There is an actual risk that the contacts may oxidise and not contact reliably when used at milliampere currents. They may need a higher "wetting current".
A machine kill switch is AFAIK 'normally closed'.
Hitting it will 'open' the switch, and that should be reliable.
60mm and 100mm arcade buttons are common on ebay, but hey, if the game show uses a kill switch...
