Dial switch for telephone sets comprising a ring-shaped dial mounted underneath the circle of holes of the fingerplate

摘要

The dial 1 exhibits locking hooks 2, 3, 4, 5 extending perpendicularly to the rest area, which lock behind rigid locking noses 7 of a carrier 6. To secure the locking hooks, the carrier exhibits elastic tongues 8, 9, 10, 11 which, when the locking hooks are introduced, avoid these and then return to their initial position so that they rest behind the locking hooks.
