HYDROSTATIC SWITCH Russian patent published in 2019 - IPC G01L19/12 H01H35/24 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of instrumentation, in particular for use in the automation systems of explosive technical objects, incorporating hydraulic systems or immersed in the aquatic environment, with which emergency situations are possible during storage and operation. Device includes a housing with a fixed elastic membrane that interacts through a rod with a contact system, and is equipped with a polarized electromagnet with two stable angular positions of the rotary armature. Radial projections are made on the end of the rod, interacting with L-shaped projections symmetrically placed on the end of the armature by axial movement of the spring-pressed stem when the diaphragm is triggered and clickable. Contact system contains U-shaped elastic contacts placed around the stem, mounted on bushings placed on the current leads of two levels. Shoulders of each contact are pressed oppositely to each other by the swivel clamps that enclose them, mounted on the ends of the bushings, and the stem is equipped with an insulator with electroconductive plates fixed in it with the possibility of their ends interacting with the shoulders of each contact. In this case, half of the sum of the angular width of the L-shaped protrusion and each radial protrusion does not exceed the angle of rotation of the armature of the polarized electromagnet.

EFFECT: technical result consists in expanding the field of application with an increase in the reliability of operation in conditions of high-intensity operational vibrations and shock accelerations, as well as safety in case of possible emergency situations.
