"""Miniature through-hole SPDT slide switch, C&K OS series OS102011: a steel shell over a phenolic base, a square actuator through a
slot in the shell, three terminals in a row and a snap-in leg at each end. MS2Q stands upright (actuator up); MA1Q is the right-angle
version (actuator along -Y, parallel to the board). The origin is at terminal 2, on the board's top face (the XY plane); the terminals
and legs lie along X. Dimensions from C&K's data sheet, in the README."""
