PROTECTIVE-ADJUSTMENT KIT OF THE PRESSURE CONTROL SWITCHER MECHANISM Russian patent published in 2018 - IPC H01H45/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in safety-adjusting kits for the mechanism of the pressure control switch. Safety-adjusting kit contains an adjusting key having a flat and a cylindrical part, and a casing with a cavity for receiving the mechanism of the pressure control switch, the casing being in the form of a body member comprising four continuous side walls and one upper horizontal wall, there are two grooves in the upper horizontal wall, made in the form of the first and second wells with walls. In the lower part of the first well there is an opening, and the second well is made blank. Wells are of different lengths, the first well being formed with a diameter pitch such that in its upper part there is a cylindrical region with a larger diameter than its lower cylindrical region, wherein the first well is adapted to receive a fixing member therein that enables the casing to be secured relative to the pressure control switch element by a threaded connection between the fixing member and the pressure control switch element. Second well is configured to accommodate a key for adjusting the mechanism of the pressure control switch, and in the upper part of the second well two diametrically opposite vertical grooves are formed to accommodate the edges of the flat part of the adjusting key in them. At the end of the cylindrical part of the adjusting key there is an opening configured for the hexagon nut of the pressure control switch mechanism.

EFFECT: technical result, to which the proposed technical solution is directed, is to provide an opportunity of operative access to the mechanism of the pressure control switch for regulating its parameters, and at the same time to protect reliably the switcher elements from external influences.
