Electric time switch (clock timer)

An electric time switch having an analog time display and a programme disc (1), which can be driven by a common clockwork via a changeover mechanism and on whose circumference radially displaceable switch elements are arranged, can be switched at any time from a weekly programme to a daily programme by swivelling a lever (6) which actuates the changeover mechanism. In addition, the scale ring (17) is removed, turned and set in such a way that the reading at the index (29) is a switching time which corresponds to the selected programme and agrees with the analog time display. For this purpose, the scale ring (17) is provided with a finely divided notched scale on the inner circle, and the programme disc (1) is provided with corresponding latching lugs (18).
