VARIABLE RESISTOR WITH CIRCULAR TRANSLATION OF MOBILE SYSTEM Russian patent published in 1997 - IPC

FIELD: radio engineering, manufacture of resistors. SUBSTANCE: variable resistor with circular translation of mobile system is composed of case from organic resin, resistive element with metal leads and rotary mobile system with spring-loaded pressing points shut in case with cover. Resistive element has upper flexible backing made of organic resin, resistive backing mounted under it, gasket placed between them with spaces of working and commutation zones. Resistive element presses against case over contour of flexible backing with realization of function of membrane unit of resistive element. Pressing points of mobile system slide over smooth surface of flexible backing. EFFECT: increased wear resistance of resistive element. 1 cl, 10 dwg
