1、The brightness of the light can be adjusted as needed, the selection range is wide, and the operation is simple and convenient. 2、The touch function can be realized in the case of isolation protection of media (such as glass, acrylic, plastic, ceramics, etc.), and the safety is high. 3、The application voltage range is wide and can be arbitrarily selected between 2.4 and 4.5V. 4、The application circuit is simple, the peripheral components are few, the processing is convenient, and the cost is low. 5、Anti-power interference and mobile phone interference characteristics are good. EFT can reach ±2KV or more; in the case of close-range and multi-angle mobile phone interference, the sensitivity and reliability of touch response are not affected. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
