ABSTRACT:
A switching device is provided, for measuring capacities, comprising n branches in parallel with n.gtoreq.1, each branch being formed by a capacity to be measured and a switch, the assembly of switches being subjected to a control signal which successively connects each capacity in parallel across the measuring bridge. Each switch may assume two positions, one of the positions connecting electrically the first plate of the capacitor to be measured to one of the ends of the measuring bridge, the other position connecting electrically the first plate to the second one and to the other end of said measuring bridge.
