ABSTRACT:
Disclosed is a rotary dial with improved mounting arrangements for assembling the dial and for securing the dial within a telephone instrument. A rotary dial using the present construction features allows one common dial base to be mounted in a number of different housing configurations. The common dial base is fabricated of molded high impact plastic into which mounting members using the present design may be snap-fitted. By providing snap-in mounting members in a plurality of slightly different configurations, the same dial may fit within a plurality of dial housings. As a further part of the improved mounting structure, an easily mountable locking ring is employed to cooperate with the dial base and snap lock a number ring firmly in place.
