You may be able to mount one of these
but you may lose the water/weather resistance of the flashlight.
Try Hosfelt or Allelectronics, online.
50-50 that replacing the switch works.
Any one or more of several inaccessible connections inside the flashlight that depend on spring pressure may be flaky.
That's the problem with low resistance circuitry like flashlights, thermocouples and 12v lighting circuits that use 50w bulbs, but even bolted connections have a non-zero contact resistance.
