How long does it take to break in a switch?

To reduce scratchiness in switches, it is possible that the switches may need an initial break in period of 2 weeks – several months depending on the switch and how consistent you use your keyboard. After that, lubing the switch will make the switch feel indefinitely better.

What happens when a break is encountered in a switch statement?
