The PARTS Premium Switch is an innovative electronic switch that seamlessly integrates with Korea’s standard vertical mounting boxes, enabling horizontal or square switch installations without additional wall modifications. Powered by patented technology, it controls up to 8 buttons using only two inserts, eliminating the need for separate inserts behind each button, as required in conventional designs. The momentary switch mechanism ensures that buttons always return to their original flush position, maintaining a clean, modern aesthetic, while the LED indicator provides clear visibility of the on/off status. Furthermore, as an electronic switch incorporating a neutral wire, the PARTS Premium Switch is IoT-ready, enabling future expansion into smart home systems. With its innovative design, easy installation, and premium aesthetics, the PARTS Premium Switch redefines lighting control for both residential and commercial spaces.
