Quartz Cuckoo Clock
A quartz cuckoo clock is a fully automated clock that doesn´t require winding. Pendulum, weights, and chains serve only as decoration, inspired from the original cuckoo clock look. Beside the cuckoo sound, these clocks have music, too, and can be silenced at night. There are two options for that: a light sensor or manual switch.
A light sensor will automatically sense a reduction of light in the house and it will silence the clock until it senses more light in the room, upon which it will automatically start the sound of cuckoo and music.
Manual switches have 3 positions; on all the time, music off, or cuckoo and music off.
