You are not wrong, but I have gotten used to the button feel.
I tell myself that since the button is just a plunger, that presses against the actual switch button internally, I think of it as “normal”.
I have had maybe half a dozen SC21 Pro, and they all have had a similar feel. I can agree you could call it a bit “mushy”, in the beginning of the button travel. I just make a point of pressing deeply and deliberately, when using the switch.
This early travel being not active against the internal switch button, actually makes me feel safer carrying unlocked. There is very little chance of the external button being pressed deeply and deliberately enough to actually trigger the internal switch, unintentionally.
Another reason I dont worry about lockout is that I disable Turbo, and only use ceiling, of 120/150. This means there is much less chance of burning a hole in my pocket IF it was possible to create an unintended button press in pocket.
Bottom line, I have gotten used to the SC21 Pro button “personality”, and it is not something I expect to be different, on a replacement light.
Thanks for sharing your impressions of the button “feel”. I have no doubt that you have experience with other button types on other lights, that make the SC21 feel “different”. (softer, and without a “clic”)
I do agree it is a tiny button and takes some getting used to. It does have some “takeup slack” as the plunger is first pressed. The SC21 Pro button definitely feels different than the short stroke button on my TS25, which has almost zero travel before it trips the internal switch button. And the TS25 button actually feels like it is clicking. Otoh, the TS25 button does not have an indicator LED, and I would feel more concern about it being pressed too easily, by accident, when in pocket…
Not all buttons are created equal… LOL
I hope you both adapt and find the SC21 Pro button functional, and predictable, when pressed deeply enough.
I actually prefer the tailswitch on the TS10, over any sideswitch button. However, the SC21 Pro has a tailmagnet and a lighted indicator switch button, so I tolerate the sideswich, for the other features of the light.
