Power must be disconnected before installation to ensure safety. The wiring should be identified according to national standards. The live wire is usually red, yellow, or green; the neutral wire is blue; and the ground wire is yellow-green. The wiring principle is "neutral on the left, live on the right, and ground on top." The common power supply method is a neutral-live wire power supply. Early products had a single live wire power supply.
Specific wiring methods must be strictly followed according to the product manual, as different brands may have different methods. Installation must be performed with the power off to avoid live wiring. Connect the existing wiring in the switch box to the corresponding terminals of the switch to be installed. A common wiring method is quick wiring, where the stripped wire ends are directly inserted into the wiring holes. Then, fix the switch panel assembly to the box and finally connect the power for testing. Ensure the ground wire is connected correctly and not incorrectly.
It is recommended to choose products from well-known brands to ensure chip sensitivity and quality. In addition to manual touch, the touch switch also supports various intelligent control modes such as remote control, voice, timing, scene linkage, and remote control. Possible causes and solutions for touchscreen malfunction include poor contact at the contacts (disconnect the power and clean the switch contacts); a damaged circuit board requires replacement (recommended to be performed by a professional); foreign objects obstructing the switch require disconnecting the power, removing the switch panel, and inspecting and removing the obstruction. Additionally, check that the power supply is normal and that the wiring connections are secure.
