Electric clock with analog time display and additional timer switch - uses timer disc positioned coaxially behind clock face

摘要

The clock, e.g. a household clock, has the timer disc, for programmed operation of the timer switch, positioned behind the clock face and coaxial with the latter, the sides of the clock housing positional closely around the periphery of each of the latter. The synchronous motor drive for the clock mechanism and the electrical installation circuit are contained within a rear casing projecting from the back of the clock housing. Spaced about the front of the housing are a number of push-buttons, each co-operating with a switch point of a contact device, operated by the timer disc, and with a respective light source for illuminating each push-button, to indicate the position of the disc.
