Abstract
An electromechanical alarm clock (42) with a variable alarm indicator (48) on a 12 hour time display, for example, of a numerical face plate (44), is designed, without the need for extensive mechanical or electromechanical setting or switching means, to operate over 24 hours, so that an alarm signal (52) will be emitted not 12 hours, but 24 hours after the setting of an alarm signal time. To this end, a blocking time circuit (75) is provided, which operates slightly longer than 12 hours if it is actuated by the manual deactivation of the alarm signal (51), and is based preferably on the counting of pulses from the time keeping clock circuit (45). The blocking time circuit (75) is also reset by a reset switch (71) when another time is set for the emission of the alarm signal, in any case if the new alarm signal emission time is set within the blocking time period (H). The reset switch (71) provided for this purpose may be combined functionally with the setting handle (73) for the setting of the alarm signal.
