analog switch

Abstract

The invention discloses an analog switch, and aims to provide an analog switch with simple structure and low cost. An analog switch that can be pasted freely on the analog screen. The feature is that one side of the bottom plate is provided with glue connected with the surface of the analog screen, and one end of a small-diameter shaft of a stepped shaft is connected on the other side of the bottom plate, and a hole is provided on the button handle, and the hole is sleeved on the stepped shaft. The outer wall of the small-diameter shaft is provided with two to twelve positioning grooves, and the hole wall of the button handle is provided with one to twelve elastic buckles each of which can be snapped into the positioning grooves. Two to twelve grooves are arranged on the inner wall at the inner end of the step hole of the button handle. The outer wall of the large-diameter shaft of the stepped shaft is provided with one to twelve protruding teeth, each of which can be snapped into a groove, and each protruding tooth is provided with an elastic relief seam around its periphery. Between the small-diameter shaft of the step shaft and the button handle hole, there is a sleeve tightly matched with the button handle. Four to eight parallel opposite sides are arranged on the outer wall of the small-diameter shaft. Open seams are provided on both sides of the button handle hole. The seam is provided with a spring buckle stuck on the parallel surface opposite the side of the small-diameter shaft.

Description

technical field [0001] The invention relates to a switch on an analog line screen. In particular, it is an analog switch that can be arbitrarily pasted on the analog screen. Background technique [0002] In the analog switch in the prior art, the button-moving shaft mechanism is arranged under the bottom plate of the analog switch, which requires a deep hole to be installed on the analog screen, thus causing the thickness of the analog screen to increase and the weight to increase. Moreover, the analog switch has many parts, high cost, and complicated production and installation. Such as Chinese Patent Publication No. CN2062120, date of disclosure on September 12, 1990, utility model name: analog switch knife switch, application number 89219379.4. Contents of the invention [0003] The invention overcomes the defects in the prior art, and proposes an analog switch that can be arbitrarily pasted on the analog screen, and its position can be changed at will. [0004] T...

AI Technical Summary

Problems solved by technology

[0002]In the analog switch in the prior art, the knob rotating shaft mechanism is located under the bottom plate of the analog switch, which requires that a deep hole must be provided on the analog screen to be installed , as a result, the thickness of the simulation screen increases and the weight increases

Moreover, the analog switch has many parts, high cost, and complicated production and installation.
