FIELD: tool-making industry, namely, engineering of informational systems and transformers of mechanical effects to optical signals. ^ SUBSTANCE: annunciator contains body containing piezo-electric element, light-emitting element, for example, light diode or neon lamp, connected in galvanic manner to each other, elastic element with two balance states, one of which is stable, while another one is not, connected by one end rigidly to the body, striker, mounted on the free end of elastic element coaxially with piezoelectric element and at fixed distance from free end of elastic element, and a pusher. Light-emitting element is connected to piezoelectric element. ^ EFFECT: expanded functional capabilities, decreased power consumption, increased durability and reliability in operation. ^ 5 dwg
