Soft switches are fine if the power is really, really, low. For real.
Like, if the battery is rechargeable, 5-25uA is pretty much zero drain.
If it's disposable, you get about 1-5uA before it's A Problem(Because the only good use for a disposable is on stuff that only gets changed once in multiple years).
In a lot of cases the switch is the least reliable part, and it makes case design harder, and maybe compromises waterproofing.
- globular-toast 5y agoBeware of alkaline cell leakage, though. They fare much better if they are isolated when not used for long periods. But you could use a low self discharge rechargeable cell like NiMH instead of alkaline, of course.
