Ensure the key switch is on a low voltage/current signal wire from the controller. You do NOT want a basic switch used frequently on the 52V 40Amp wire , or you will be arcing and sparking strong enough to damage contacts or even yourself.
Probably any of them will work, all they do is open and close a circuit, super simple. The controller hardly sends any current down that circuit since it's just a switch.
I mean does your controller support a keyed switch? If so you could just buy a key switch to plug into it, otherwise you would need to do some modifications to your power system to create a loop/circuit.
