INERTIAL CIRCUIT CLOSER Russian patent published in 2002 - IPC

FIELD: flying vehicle automatic control systems and motor vehicle safety systems. SUBSTANCE: circuit closer used in measuring acting linear accelerations has case, axle-mounted inertial body held in position by means of magnetic system, contacts and their rotary operating mechanism provided with slot on its side wall. Case is provided with tilted slot engageable with one projection on inertial body; extreme corner surfaces of slot in side wall of rotary operating mechanism are parallel to inertial body axis for turning rotary operating mechanism by means of other projection of inertial body during its forward and reverse travel at the end of travel only. EFFECT: enhanced operating reliability at great number of contacts; prevented unwanted operation at high-frequency vibration impacts. 4 dwg
