Thanks all for the replies. I do feel the problem is probably in the switch. Can this be replaced?

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.

Check that link, instructions on replacing switch.

In future, removing severly swelled corroded batteries, Drill thru bottom of battery, pry out metal bottom, use spade bit in ratchet and socket to hollow out battery. Thin screw drivers, needle nose pliers to remove case. Do not use vinegar. Solution of baking soda and water, soap and water, and/or, PB Blaster.

The OP can also go on Candlepower Forums.
Those guys love flashlights and guns; one throws photons, the other throws lead pellets.

Spray photons with PB Blaster, they come out of model 1847 Colt Revolver ( Walker Colt) with extra power, knocks Klingons onto both of their backside. Do not get PB on black powder, causes ammo to spin opposite direction of rifling in barrel, warping space-time continuum, killing your grandfater before you were born, vinegar on percussion caps causes Maglites to emit darkness instead of light.
