Questions

What is lubing a switch?
Lubing a switch involves coating the switch's stem, the part that makes contact with the inner housings of the switch, with a nonconductive material, usually oil, grease, or a mix of the two. The result is that the switch ends up feeling smoother on its travel.

Where do you lube?
I lube both sides of the stem, where they hit the bottom housing on the sides, the hole where the stem goes into as well as contact points for the spring. On linears, I will also lube the legs that hit the contact leaf, but on tactiles, I tend to stay away from it because users report dulled tactility when I lube it.

How long does it take to lube a switch?
About a minute each, but it varies by switch.

Should I lube?

Yeah.

What happens if a product arrives and is broken?
This can always happen, due to either factory error, my error, or shipping errors.
