Product Advantages

This key operated metal rotary switch is available in 19mm and 22mm two mainstream mounting sizes, compatible with most industrial control panels. It supports 2-position and 3-position switching, and provides two classic contact combinations to meet different circuit requirements. The whole switch adopts metal bezel and chromium plated brass shell, which is solid, anti-rust and durable. Gold contacts and pins effectively avoid oxidation and ensure stable electrical transmission. Adopting welding connection, the wiring is firm and not easy to loose. The flat key head with locking function can effectively restrict unauthorized operation and improve equipment safety. Non-illuminated design simplifies the structure and reduces failure points, which is an ideal security switching component for industrial equipment.

Applications

• Industrial control panel key-locked power and circuit switching control
• Automation equipment permission management and anti-misoperation switch
• Electrical cabinet and distribution box locking type rotary selector switch
• Mechanical equipment operating panel safety access control component
• Public equipment and special machinery security locking switch
