Product Advantages

This 16mm rotary selector switch is a multi-functional industrial control component. It provides two position choices (2-position and 3-position) and two operation modes (maintained and momentary), which can adapt to different circuit control logic. Adopting classic 1NO1NC contact combination and high-purity silver contacts, the switch ensures excellent electrical conductivity and long-term anti-oxidation performance. The plastic bezel and shell feature good insulation and shock resistance, suitable for conventional industrial working environments. The 16mm standard size is highly universal and compatible with most industrial control panels. The black non-illuminated rotary head has a simple and durable structure, without easily damaged lamp components, effectively reducing failure rate. The product is easy to install and wire, with compact layout, which is an economical and practical choice for equipment gear switching and circuit selection. It meets the usage requirements of industrial fields around the world.
