Switch housings, compared: nylon, polycarbonate, POM, and the rest

The housing line on a switch spec sheet is the second-most-important thing about a switch, after the type, and most buyers skim past it. Material decides how the switch rings, how the stem rails feel under a finger, and how much grace it gives a bad lube job. A 'PC top, nylon bottom' tag is doing more work than its three words suggest.
