One thing German manufacturers needed to clarify when building clocks was which way the shut-off switches work. Many manufacturers have tried with different kinds of markings on stickers placed near the shut-off switches. But what if these stickers come off? Or, what if they come off and are put back on upside down?
Here is an easy way to tell if your chime/cuckoo is turned off or on:
The way to tell if the shut-off switch is in the correct position is to listen for a “click” when moving the minute (larger) hand slowly clockwise past the hour or half hour. If there is a click=the shut-off is on, no click=the shut-off is off. Sometimes the sticker next to the shut-off switch can be confusing. It is best not to trust this sticker, and to go by the simple gauge (click=on, no click=off)
