The Velleman electric piezo buzzers are specifically designed for applications requiring a highly reliable alarm or signal with a completely solid state and no electromechanical contact (oscillating circuit is built in). They are replacing the conventional electromagnetic buzzers because of their low power consumption, the extremely clear and penetrating sound, the absence of electrical noise, their compact design and their limited weight. A variety of models is available for various tone functions.
