Automatic switch for multi-valued electrical resistance

Claims

1. An automatic switch (AS) for a multi-valued electrical resistance measure (MMES), comprising a housing in which a supporting panel is placed, with a system for moving the AS drives with stepper motors and a control controller located on it, characterized in that the design of the AS drives of the decades is made in the form of a two-coordinate rectangle from the supporting guides forming it, two sides of which, for example, vertical, are fixedly fixed on the panel, and the second two guides, for example, horizontal, are made movable and fixed in carriages moving along fixed guides, the drives with stepper motors are mounted on movable brackets and move independently of each other in one direction along the movable guides and dependently along the rows in the second direction along the fixed guides, providing the possibility of automatic control of various types of MMES with manual switching,with different interaxial distances of decade switches, 2. An automatic switch for a multi-valued measure of electrical resistance according to paragraph 1, characterized in that replaceable adapters are installed, the shape of the inner surface of which precisely corresponds to the shape of the outer surface of the handles of the decade switches of the MMES of a specific type, connected to the axis of the electric motor by floating couplings, which ensure precise alignment of the axes of the APMS drives with the axes of the handles of the decade switches of the MMES.

3. An automatic switch for a multi-valued measure of electrical resistance according to paragraph 2, characterized in that the metric scales with dotted markings, applied along the axes of movement and forming a coordinate grid on the instrument panel, ensure the precise setting of the device drives for a specific type of MMES.
