FIELD: physics, signalling.
SUBSTANCE: invention relates to signalling devices operating in vibration, linear and impact action conditions, and can be used to secure premises and facilities for different purposes. The device comprises a housing, a spring-loaded movable element having first and second arresters, an electric signal former in the form of a magnetoelectric generator and a rotary double-arm lever pressed to a support. The double-arm lever is capable of fixing the movable element through the second arrester in a pre-armed condition of the signalling device and freeing the movable element in an armed condition. The shaft of the magnetoelectric generator on one side is capable of fixing it in pre-armed and armed conditions by the movable element through a level mounted on the shaft, and on the other side interacting with an additional drive with stored energy.
EFFECT: high reliability of the device in vibration, linear and impact action conditions.
