An electrically driven decimal counter adapted to count motions such as revolutions, and to control various operations in a predetermined number of repeating steps. At least two rotatable counting members are mounted for relative movement along their common axis so as selectively to be drivingly connected and disengaged. One of the counting members carries means for controlling a first switch mechanism for transferring impulses to the next stage of the counter, such switch mechanism also receiving zeroing impulses. The other counting member has a means for controlling a second switch mechanism, which is adapted to be interposed in an electric circuit for a machine. The mechanism for disengaging the one counting member from the second constitutes a mechanical controlling member for the second counting member. |
