SWITCH Russian patent published in 2009 - IPC H01H19/02 

FIELD: electric engineering.

SUBSTANCE: invention is related to measurement equipment, in particular to design of switches used in multidigit measures of electric resistance and measurement bridges. Switch comprises panel (9) with commutation (10) and distributed common (11) contacts, axis of switch (16), bearing cross beam (13), on which brush unit (14) is installed, comprising flat independent conductive disks installed with gap on axis of cross beam (15). During contact disks of brush unit (14) close one of commutation (10) and common (11) contacts, at the same time providing for minimum transitional resistance of contact pair and fixation of switch position.

EFFECT: simplified design, reduced material intensity and labour intensity of manufacturing with preservation of main electric characteristics of switch: transitional resistance of contact pairs and their variation at the level of prototype.
