ACCELERATION LIMIT SENSOR Russian patent published in 2016 - IPC G01P15/135 G01P15/06 H01H35/14 

FIELD: instrument making.

SUBSTANCE: invention relates to inertial sensors threshold action for recording and storage in autonomous mode (without power supply) information about acceleration preset limit levels. Acceleration limit sensor comprises a body with inertia body is pressed to stop elastic element installed with possibility of transition from one stable position to another by snapping. Elastic element is made in form of flexible plate spring with edge corrugations, having at section of working stroke of negative stiffness of central hole of plate spring is installed an inertial body of spherical shape.

EFFECT: high accuracy of sensor actuation under action of accelerations acting along and at an angle to axis of sensor, including impact pulses of arbitrary shape, and high stability under conditions of vibration loading.
