SureFire D3FT Combat Flashlight – switch options

I have a SureFire D3FT Combat Flashlight. I'm overall happy with its size and brightness. I am not happy with its switch. on a couple of occasions I have felt it on in my pocket, gets toasty. which of course kills the battery.

What is a compatible SureFire momentary press on, twist on constant switch? Preferably something that doesn't require as much pressure as a Tactician switch (If it's even compatible).

This light only comes out just before, or in conjunction with my pistol. I need it to work when I pull it out.
