They may come with a 3 stack switch but not with the 2.
I ordered them from electroswitch, pack of 25 is only like $5.
I looked all over there website last night but couldn't find them. I called the # provided but they said it was a different division in MA that had them, so they gave me the correct # to call.
KR also has them, talked to mike, the #'s he gave don't show up on there website but he says they do have them in stock.
