The circuit arrangement comprises an operation control circuit (7) in a time-measuring instrument, which can be switched over by an actuator which can be operated by hand and has a plurality of switch positions. The operation control circuit (7) is assigned a protective control circuit for generating during the movement of the actuator from one switch position to an adjacent one a switchover delay time which can be given a fixed setting. In this case, a delay time signal is generated which is of a prescribed length and which preferably lasts beyond the normal switching time, in order to suppress instantaneous maloperations, without in the process having to accept an unnecessarily long delay to the start of functioning of the operation control circuit. <IMAGE> |
