Four Wires & Unknown Switch

I am attempting to replace a switch in my basement bathroom which turns on the bathroom lights and the bathroom fan. When I test the wires using a non-contact voltage tester the black wire with the purple cap is hot - but all the other wires are also hot but with a low voltage. When I connect the black and white wires on the right hand side to a light switch the sparks fly and the fuse blows. What is the proper switch for this type of setup? Thanks

Welcome to the forums!

Normally the whites are tied together with a nut and the two blacks go to the switch. It really doesn't matter which black goes to which screw, but common practice is to place the hot (purple) on the top screw.
