ACCELERATIVE SWITCH Russian patent published in 2009 - IPC H01H35/14 

FIELD: automation.

SUBSTANCE: invention relates to accelerative switch for automation systems of different technical objects, subject to impact of linear acceleration. Accelerative switch contains case (1) with cover (2), which form tank filled by liquid (11), in which it is located accelerative body (6) in the form of flat disc, held by magnetic system (8) and stationary contacts (4). Accelerative body (6) is movable contact, implemented of bimetallic material with location of active layer (7) from side of circumferential located stationary contacts (4) and is fixed with ability of movement up to strapping of stationary contacts (4). For increasing of accelerative body mass (6) on it is fixed magnetic system (8), and on body (1) by thread of screw it is installed cover (9) made of magnetically conductive material, which is bypass of magnetic system.

EFFECT: reliability enhancement by means of actuation time stabilisation in wide range of operation temperatures, reduction of actuation inaccuracy at accelerations in side directions and providing of setting for small predetermined level of actuation, and also exclusion of adjusting of contacts attitude during adjustment.
