INERTIA SWITCH Russian patent published in 2015 - IPC H01H35/14 

FIELD: machine building.

SUBSTANCE: switch is fitted with an external sleeve, coaxially located between fixed guide and mobile rotary drive with a possibility of rotation with reference to them and with a slant slot on a side wall. The switch is fitted with a sleeve, spring-loaded and enclosing an inertial body, the radial protuberances of which interact with slots of the rotary drive, external sleeve and fixed guide. One protuberance from the inside interacts with the inertial body when it moves along the guiding axis. The slots in the external sleeve and in the fixed guide are designed with a slope in opposite sides. The slot in a mobile rotary drive is designed with walls parallel to a guiding axis. From the side of one end of the fixed guide the permanent magnets with magnetic conductors are installed. The fixed guide is made from non-magnetic metal, and external sleeve - from non-magnetic metal with high electrical conductance.

EFFECT: improvement of reliability of operation of the switch at high intensity shock and vibration accelerations and keeping of the initial state of contacts at accident fallings within the structure of the used object.
