Embodiment Construction
[0013] In order to further describe the technical features and effects of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] refer to figure 1 , a multi-level potentiometer, including an insulating base 1, a rotating shaft 3, a conductive swing arm 2, a number of resistors 4 with different resistance values, a gear switch 5, a fixed pin 6, and a fixed pin 2 7. The pin 8 of the movable piece, in order to achieve a good insulation effect, the insulating base 1 adopts a mica sheet, and the resistor body 4 is arranged on the insulating base 1, and there are three in total, which are arranged in parallel with each other, in order to prevent the resistor body from 4 interfere with each other, and keep a distance of 2 mm between two adjacent resistor bodies 4 . In order to have a wider adjustment range in a limited space, the resistor body 4 adopts a semi-circular ring, and one...
