Abstract

A whole plastic packaging switching potentiometer mainly comprises a rotating shaft, a switch cam, an upper linking seat and a pedestal. The switch cam is in clip connection with the rotating shaft, and the rotating shaft and the switch cam are sleeved in a rotating aperture together. A rotating shaft nut cap pressed by an injection moulding supersonic wave melt pressure technology is arranged ona head of the rotating shaft, so that the head of the rotating shaft and the rotating shaft nut cap are connected integrally. A spring sheet is arranged on a lower end of the other side of the rotating shaft, and between the rotating shaft and the pedestal. Two weld tabs used for external connection are arranged on the pedestal, and the pedestal and the upper linking seat are connected integrally, in a whole plastic packaging mode, through an injection moulding supersonic wave melt pressure technology. The invention not only has characteristics of stable performance, good high voltage resistance, low costs, but also has effects of dust proof and moisture proof, etc.

Description

technical field [0001] The invention relates to a switch potentiometer, in particular to a fully plastic-encapsulated switch potentiometer, which belongs to an electronic component. Background technique [0002] Potentiometer is a widely used electronic component, and its structure will vary greatly according to different manufactures. Among them, switch potentiometers are widely used in various electronic potentiometers, but currently on the market with switches The potentiometer has complex structure, high cost and poor stability. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a fully plastic-enclosed switch potentiometer with stable performance, good high-voltage resistance effect, high sealing performance and low cost. [0004] The object of the present invention is achieved through the following technical solution, which mainly includes a rotating shaft, a switch cam, an upper joint ...
