A resounding yes: push out the top part of the switch (where the lamp pushes in) from the inside of the housing (look on Amazon if you want to see what the thing looks like): I used a single piece of steel wire (in my case .044"/1,1mm). it came our easily though getting the wire in to the little hole inside the body was a bit fussy, then drop or shake out the inner body. Once out: either clean up the mess left by the leaky battery or as in my case, since the thing was made wrong in the first place and wouldn't shut OFF, file off a bit off the outer edge of the contact, drop it back in , and reinsert the top/outer part of the switch. Done!! I suspect this also works on the larger 2AA versions. Of course, you are still stuck with those useless and very expensive lamps which, due to metallization of the inside of the glass from filament evaporation don't even last as long as the batteries. I don't understand why the replacement parts are so expensive: I could make them easily with my little unimat lathe and a few appropriate connector parts.
Also, go for the LED version even if it costs a fortune ( or, if your stomach allows it: buy an el cheapo chinese knockoff.)
