INERTIAL SWITCH Russian patent published in 2019 - IPC H01H35/14 

FIELD: electrical engineering.

SUBSTANCE: invention is intended for commutation of electric circuits with passage of high currents in systems of autonomous technical objects moving at the initial section with significant pulse acceleration under action of forces from various types of accelerating devices. Inertial switch includes a housing, in which a spring-loaded stop is installed, which interacts with a conical surface with a ball holding it, contacts which are commutated by the conducting surface of the stopper. Body is made in the form of a guiding bush, inside of which the main stopper is placed coaxially, and an additional stopper in the form of a female bushing is installed outside. Ball interacting with conical surface of the main stopper is installed in the inclined hole made in the housing wall, the inclination angle of which to the longitudinal axis of the housing is less than the angle of conical surface of the main stop interacting with the ball. From the main stopper end, made with two areas of the support surface on the outer diameter, the lower of which is made spherical, insulator is fixed with an electrically conducting ring interacting with the main stop moving the spring to the upper zone of the support surface exit from the body hole with fixed contacts fixed on the terminals. Contact surface of fixed contacts is tapered. Main retainer is composite with internal threaded rod.

EFFECT: increase in the safety.
