The problem is, when the button gets stuck - it has enough pressure to perform action in the UI light. Also clicking is not „satisfying enough”, when pressed off-center.
I have a few of these lights and they all do the same. It’s to do with the floating switch design but it only happens for me if I purposely push down at the edge of the button with a finger nail. If I just use my thumb as normal, it never happens. Out 8 lights, only one stays on when this happens so it does appear there may be a slight difference in tolerance.
