Abstract
Abstract A telephone dial is quickly and easily mounted in a housing by brackets which clip into supports forming part of the housing. The brackets are assembled to the dial before mounting permitting easier assembly and closer positioning of items in the housing. The dial is readily removed for servicing or replacement. As a further feature the brackets form an opposed pair and by changing over assembly positions, dials of different widths can be accommodated.
