Description

Technical Field

[0001] The invention relates to the technical field of touch switch accessories, in particular to a touch switch capable of displaying different panel contents at the same position. Background Art

[0002] Touch switches are classified into resistive touch switches and capacitive touch switches according to the switch principle, and are divided into single-live touch switches and two-wire touch switches (live and neutral) according to the wiring method. Globally, most countries adopt the single-live wiring rule. Therefore, early touch switches were dominated by single-live control. With the deepening of application, the stability of neutral and live control is higher, and the load of the switch is larger. Currently, the market is dominated by neutral and live control.

[0006] Preferably, the touch circuit board is manufactured using transparent conductive paste and silver paste.

[0007] Preferably, the touch pattern printed with special ink is electrically connected to the touch panel.

[0008] Preferably, the LED light source layer is formed by pressing PVC light-transmitting material.

[0009] Preferably, the LED light emitting diode is connected to the power switch via a wire.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses LED light emitting diodes on flexible circuits to provide light sources, eliminates the assembly of PCB and liquid crystal screen, cancels the liquid crystal screen and PCB board, reduces supporting costs, and the PCB and liquid crystal screen manufacturing processes belong to polluting industries, which indirectly reduces environmental pollution. A transparent electrode design scheme is adopted to ensure that the display effect can be clearly seen after the lower light source irradiates the key. After determining the LED light emitting diode, the ink is debugged according to the wavelength of the spectrum to ensure the matching of the ink and the light source. The device displays different text effects on the decorative panel at the same position, and matches the touch key effect, thereby improving the usage rate and touch feel of the product interface. Such products optimize the design interface, break through the conventional single display process, provide space for the client to realize more functions, improve the product market competitiveness, and continuously meet the needs of customers and consumers.
