Abstract

Abstract A mounting for a dial in a telephone set comprises two sets of interengaging brackets, support brackets extending up from the bottom surface of the telephone set base and mounting brackets extending down from the dial assembly. Each support bracket has spaced guide surfaces and a latch member having a downwardly facing latch surface. Each mounting bracket has guide surfaces for cooperation with the guide surfaces on the support brackets and a recess into which a latch member can engage. At least one latch member is resiliently deflectable. The dial assembly is mounted by aligning the guide surfaces and pushing down on the dial assembly, the latch members snapping into the recesses. No access to screws or other fastenings is required. One of the support brackets can be integral with a side wall of the base.
