HYDROSTATIC SWITCH Russian patent published in 2019 - IPC G01L19/12 G01L19/02 H01H35/24 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrument making, in particular for use in automation systems of technical objects, which include hydraulic systems or submersible in an aqueous medium. Hydrostatic switch comprises housing with fixed elastic membrane interacting via rod with contact system. Contact system contains elastic contacts arranged around the rod and fixed at the terminals. Each terminal has a threaded end with screwed at least two nuts, between which a resilient contact is fixed. Rod is equipped with an insulator with electroconductive plates fixed on it with the possibility of their interaction with free arms of the said contacts by means of axial movement of the spring pressed by the spring at operation of the membrane made perforated. Contacts are arranged on two levels above and below the electroconductive plates, and the rod is made with a central thickening connected to the insulator along the thread.

EFFECT: wider field of use ensuring universality of the structure by combining the number of closing and opening contacts required for each application object and improving manufacturability owing to providing a wide range of axial control and adjustment of initial arrangement of structural elements.
