CIRCUIT OF RESISTIVE ELEMENTS COMMUTATION Russian patent published in 2009 - IPC G01R17/00 

FIELD: measurement equipment.

SUBSTANCE: invention is related to measurement equipment, in particular to circuits of resistive elements commutation, used in multidigit measures of electric resistance and in measurement bridges. Circuit of resistive elements commutation comprises chains of resistive elements 5 and 7, switches 6 and 8 and connecting conductors 9 and 10, connection of which between common contacts of switches and connected together with the last outputs of the last resistive elements and the last contacts of switches, make it possible to obtain a positive technical result.

EFFECT: possibility to use simple switches in commutation circuit without complex structural provision of electric circuits commutation without their rupture, and also reduction of transition resistance and their variation after switches connection into commutation circuit.
