ABSTRACT:
This invention has for its object to activate buzzers and lamps provided in warning and signalling apparatuses for automotive vehicles by the vibration of a common source such as to simplify the construction as well as to ensure reliable function. This invention resides in electrically stimulating a tiny quartz-oscillator sealed in a capsule to vibrate at an ultra-high frequency, passing the signal from the oscillator through a frequency-divider so as to split it into a number of lesser frequency signals, amplifying them and feeding appropriate signals to buzzers and lamps.
