Contact legs, tip to tip: ca. 14 mm; hole centre to hole centre at switch base appears to be the same (first time around I got 13.80 mm but currently I'm concurring on 14 mm for two separate switches)
Lid legs, tip to tip: 11.50 mm for one, and 12.50 mm for another — these legs get bent readily, so 12 mm hole spacing sounds correct. The lid legs are 12.9 mm apart (between outer edges) at the sides, before they splay out.
Vertical: 3 mm
