SK68 switches are replaceable. You can buy the switch modules, including the switch and a fresh plastic retaining ring and washer for them. I have a bag of replacements at home.
Kaidomain sells them. Unfortunately the link has an underscore in it and if I try cutting and pasting only half the link appears. But it’s on page 2 of their reverse clicky switch section.
That said. Not everyone wants to spend $2.48 on spare parts for a $5 flashlight, so OP’s solution works.
