Abstract

The invention allows to extend the functionality of the resistor and reduce its size. On the inner face surfaces 2 and 3, arc-shaped resistive element 4 with leads and current pickup element 7 with a display are mirrored. The switch (B) is implemented in the form of specularly located on the inner end surfaces 2 and 3 of the arcuate current collector elements 12 and 13 and the contact element 14 located at the end of the current collector 10. The position of the rotating axis 9 determines the resistance change between the 13 and higher positions of the resistive element 4 It is shown in the design of the withdrawal element 7. At the same time, a stop is provided in the design that prevents axis 9 from performing more than one revolution. B works simultaneously with a variable resistor, i.e. when the contact element 14 closes the arcuate collector elements 12 and 13 when the axis 9 is rotated. Thus, by placing B in the same housing with a variable resistor, when the axis 9 is rotated, from the initial position, for example, power will be supplied first, for example value of resistance. 4 il. with (L with:

The housing (not shown) of the variable resistor consists of a cylindrical rim 1, which holds the bottom 2 and the cover 3, made of a dielectric material.

On the inner end surface of the bottom 2 there is an arcuate (in 25 strip form constituting part of a circular arc) resistive element 4 with steps 5 and 6, and on the inner end surface of the cover 3 a mirror-like resistive element 4 is arcuate collector 7 with probe.

The resistor also includes an axis 9, at the end of which in the middle part of the body there is a current collector 10 bonded to it, made of a dielectric material with a contact element 11 placed at its end, which is arranged with elastic interaction with both the arcuate resistive element 4 and the arcuate current-collecting element 7.

Structurally, the contact element 11 can be made in the form of an elastic metal spacer (the jumper pin of a variable resistor can serve either view 5 or 2Q 6, and the other is pin 8. If output pin 5 is used, then when the axis 9 rotates, contact pin 1I connects resistive element 4 to conclusion 8.

8, depending on the position of the axis 9, the resistance value between outputs 5 and 8 varies.

The limiter 19 does not allow the axis

The jack operates simultaneously with the variable resistor as follows.

Let the current collector 10 be in its initial position: its additional contact element, more precisely, its contact areas are located in urines 15 and 16.

If voltage is applied to pin 17, then at pin 18 it is wired only if contact element 14 closes the additional arcuate current-collecting elements 12 and 13 when the axis 9 is rotated.

Thus, the variable resistor can be designed so that. when turning the y-axis from the original
