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

FIELD: electricity.

SUBSTANCE: inertia-type switch includes housing, an inertia block arranged on a central axis, a fixed guide having inclined slots on side walls, contacts, a bridging device and a turning drive of contacts. A switch is provided with a sleeve with radial projections, which is fixed on the inertia block, and an external sleeve with inclined slots, which is coaxially located between the fixed guide and the sleeve pressed by a spring. On end faces on the fixed guide there arranged in a circumferential direction are two groups of constant magnets of alternating polarity, between the poles of which cylindrical rings are located, which are made from material with high electrical conductivity and fixed on the end faces of the external sleeve. Slots on side walls of the fixed guide and the external sleeve are inclined to mutually opposite sides and interact with radial projections of the sleeve. The drive is provided with a radial projection fixed on the central axis and entering the slot of the inertia block with a possibility of its axial movement. On the end of the central axis a disk with a slot on outside diameter for entering of a turning lever of a gear sector is arranged, which interacts through a gear transmission with a bridging device of contacts, which is pressed by the spring.

EFFECT: enlarging the application by provision of serviceability of an inertia-type switch at action of high-intensity impact and vibration accelerations at flight and preservation of initial state of contacts at emergency falls as part of an object of use.
