The remote control switch uses wireless radio frequency technology with an operating frequency of 433MHz, enabling long-distance remote control. The signal can reach up to 50 meters in open areas without interference and is capable of penetrating walls, doors, and floors, providing stable performance. The RF wireless remote control switch is constructed from high-quality ABS and metal materials, featuring reliable modules that ensure stable operation, durability, and ease of use. To clear the code, press the AB keys simultaneously, then continue holding the A key while pressing the B key three times in succession. Continuous flashing of the indicator light indicates successful code clearing, preparing the device for copying. For copying, press a button on the original remote control and a corresponding button on the duplicator (e.g., button A) at the same time. The indicator light will flash several times to confirm successful copying. For one-to-one code matching, press the buttons on both remotes simultaneously. When the indicator light on the duplicator remains steadily lit, code matching is complete. This universal remote control is suitable for various applications including electric gates, garage doors, smart home systems, electric doors, lighting controls, and other compatible remote-controlled devices.
