I was just wondering on what you guys use if you've ever added a key to a battery pack?

The former requires a switch that can handle the inrush current of charging the caps in the controller, at the voltage the battery is fully charged at, without welding the contacts shut or burning them, as well as the peak and continuous currents the controller will draw while in use. That's a fairly large switch for an ebike.
I use a harbor freight battery cutoff switch, with a big red plastic handle key, on SB Cruiser, and it's been working fine for a couple of years of this so far (peaks of over 120A under some circumstances in various experiments, continous of 18-20A).

it has AWG 16 tiny wirs soldered to it?
I and majority here use AWG10 size.
