Product Advantages

This 16mm miniature rotary switch is specially designed for compact electronic and electrical equipment. The ultra-small 16mm mounting size perfectly adapts to narrow installation spaces that regular switches cannot fit. It supports 2-position and 3-position gears, together with latching and momentary dual working modes, which can satisfy various temporary triggering and fixed control needs. The 3-pin plug-in terminal greatly improves assembly efficiency and facilitates later maintenance. Equipped with two mainstream contact combinations, it can be applied to single and dual circuit designs. Silver pins ensure stable current transmission and resist oxidation during long-term use. Adopting high-insulation engineering plastic, the whole body features light weight, impact resistance and corrosion resistance. This product provides two protection grades: IP40 for ordinary dust-proof workshops and IP65 for humid & splash-prone environments, with strong scene adaptability. Without LED and smart components, the internal structure is simpler and the failure rate is lower. Multiple knob colors support personalized equipment matching. With a wide temperature range, it can operate reliably in most conventional working environments. It is a cost-effective miniature control component widely recognized in global small equipment and electronic fields.
