Abstract

An improved counter assembly comprises an electrically operable counter module insert, a transparent viewing crystal, and an outer box-like case which are held together by an improved mechanical arrangement. The outer case is provided with inwardly projecting abutments engageable by the counter module insert for aligning the insert within the case. The counter module insert includes a pair of laterally spaced rearwardly facing shoulders at its front end, and the crystal includes a pair of laterally spaced rearwardly projecting retention fingers engageable with the shoulders of the module insert for retaining the case, crystal and module insert in an assembled relationship. The improved construction provides increased resistance to tampering.
