The TS-12 does indeed feature a vandal resistant button versus the plastic button from the TS-2 - but my personal concern is humidity and the lack of a weatherring for these push buttons and in my opinion using a 302 faceplate (a better grade of stainless) is not addressing the issue.
Please explain the application adnd where this is used along with what other hardware is involved. I would like to make the best possible suggestion for your application and need for an exterior rated push button.
