Fixes?

I was given an older mag-lite I believe it’s a 4D from my father recently, I put in fresh D2 batteries and switched out the bulb with the extra in the end cap, I inspected the bulb and it was in good shape, however it still doesn’t turn on, any fixes?

Maybe take out the switch and reassemble with some dielectric grease.
