Embodiment Construction

[0016] Membrane switch with window antistatic function of the present invention such as figure 1 As shown, the same as the prior art is that it is pasted sequentially from bottom to top with a primer layer 1, a lower circuit layer 2, a wire bond layer 3, an electrostatic layer 9, a surface bond layer 4, and a panel layer 5. The bottom rubber layer 1, the line key layer 3 and the surface key layer 4 are all double-sided adhesives. The bottom surface of the bottom rubber layer 1 can be pasted on the PCB board of the product. 3. The surface key layer 4 has a hole corresponding to the switch button sheet 6, and a transparent window 7 is provided on the panel layer 5. The surface key layer 4, the electrostatic layer 9, and the line key layer 3 below the transparent window 7, Corresponding openings are opened on the lower circuit layer 2 and the primer layer 1 . Different from the prior art, a transparent conductive sheet 8 is provided in the opening of the surface key layer 4, and...

Abstract

The invention discloses a membrane switch with a window antistatic function, comprising a primer layer, a lower circuit layer, a line key layer, a static layer, a surface key layer and a faceplate layer which are successively pasted from bottom to top. The lower circuit layer is provided with a switch key sheet; the faceplate layer is provided with a transparent window; the surface key layer, the static layer, the line key layer, the lower circuit layer and the primer layer under the transparent window are provided with corresponding holes; a transparent conducting strip is arranged in the hole of the surface key layer; one end of the static layer leads out the membrane switch and is grounding; the transparent conducting strip is conductively pasted to the transparent window and the static layer. According to test evidence, the membrane switch can substantially increase the antistatic grade of a product transparent window, and allows a product to be effectively applied to various occasions with greater static electricity.

Description

technical field [0001] The invention belongs to a membrane switch, in particular to a membrane switch with a window antistatic function. Background technique [0002] With the continuous expansion of membrane switch market applications, its technical requirements in various industries are also increasing. Because membrane switches are widely used in industries such as industrial equipment, in some high-voltage application environments, customers' requirements for anti-static membrane switches are also constantly increasing, especially for anti-static products at product windows. The technical requirements are very high. At present, conventional membrane switches in the industry cannot meet this requirement, and there is no relevant product and technical verification. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a membrane switch with window antistatic function, so as to effectively solve the antistatic proble...
