Cordless Screwdriver Switch Re-Repair

The switch on that screwdriver failed again, this time by having the internal switch mounting bosses disintegrate:

Not being one to worry about outside appearances, I simply drilled out the bosses to fit a pair of 4-40 screws, put the nuts inside, and it was all good:

Except that the switch now required an unseemly amount of force to operate in the forward direction. The switch is the cheapest possible collection of bent metal strips and injection molded plastic bits you can imagine, but with some bending and re-staking and general futzing around, it works fine again.

This still makes no economic senseā€¦
