Hey guys Im trying to Make a On/Off switch out of any of these 3:


and the back..



Have any of you done something similar to this?
Im still not sure what the switch is going to be for... maybe add some lights inside and to turn lights inside on/off, fuel pump switch?, city light light switch,... just dont know yet lol.
Since they are just laying around in my garage i thought might as well do something with em..

Ps sorry bout crappy cell phone pics.
Thanks for any help
