INERTIAL CLOSING SWITCH Russian patent published in 2022 - IPC H01H35/14 

FIELD: instrumentation.

SUBSTANCE: inertial closing switch comprises a tightly sealed body filled with damping fluid with an inertial body compressed by a spring and a contact system with a connector placed in said sealed body. A cylindrical guide is installed in the body along the central axis, whereon the inertial body and the connector of the contact system are placed coaxially, wherein the spring mutually expressing the inertial body and the connector is placed between them. Permanent magnets with opposite poles facing each other are secured on the ends of the inertial body and the connector facing each other. A protrusion limiting the axial movement of the inertial body and the connector towards each other is provided on the cylindrical guide.

EFFECT: higher reliability of maintaining the initial state in operational use and in emergencies and higher reliability of triggering as part of an object of application.
