The switch you are looking to replace a Mag switch may end up being the Mag switch
Mag D witch, forward clickie, can handle 9A after resistance mod. I had this light for over a yr before I sold it. It had a mag stock switch. Resistance mod on everything except the core ring. With fresh batteries, it starts out close to 9A.

I did recall seeing a thread on modding the Mag switch to take high currents but I can't seem to find the thread. I do remember solder wick being used.
Will the Petrev/JimmyM MOSFET D Mag switch mod work? It's a fairly simple switch mod, although you do need a Kiu socket kit as well.
That circuit diagram was how I pictured it, except with different resistor values, the gate shouldn't require much current to activate. You might be able to make is smaller depending on the size of your parts. You might not need a PCB, but then you'll have to be careful of shorts. Also, if you are using a maglite, switch the spring to a lower resistance one.
