CONTROL PANEL Russian patent published in 2020 - IPC G06F3/23 H01H13/70 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrument making, particularly to push-button control panels. For this purpose, a control panel is proposed, which comprises a housing with buttons, a contact group arranged in the housing, which is closed from pressing by buttons and sealed with a protective element. Internal volume of housing is filled with dielectric liquid with operating temperature range from minus 60 °C to plus 200 °C and is equipped with sealed resilient membrane. Membrane is located in the housing so that its inner surface is in contact with the dielectric liquid and interacts with the external medium through the hole in the housing. Contact group contains convex elastic elements free of pressing of buttons, at that under the elastic elements there are conducting sections, and also contains switching current-conducting paths. Protective element is made in the form of a plate which tightly closes the contact group from the external medium.

EFFECT: providing reliability of operation in air and water environment without restrictions on depth of immersion and height above sea level, as well as on ambient temperature.
