(Click on image to see a closer view)
When you open the glass door of the clock you can see a small shelf near the bottom of the clock. On the right side of the shelf is the spring motor. It is connected to the program disk located on the left side. Contact springs and a revolvable drum fit between the program disk and the motor. The program disk, motor, switch and trip mechanism can be seen in more detail in the next slides and in Figure 2.
