[Product Overview] 16mm opening diameter, 16F flat-head ring-type power symbol illuminated latching metal push button switch (SPDT 1NO1NC / 5-pin terminal / stainless steel or brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)

16F flat-head ring-type power symbol illuminated latching metal push button switch (Metal Push Button Switch 16mm Flat Cap / Power Symbol Illuminated Latching Switch 1NO1NC) is a product specifically designed for Industrial control cabinet main power switch, high-end instruments and equipment, industrial control hosts, medical equipment, and automation equipment A highly recognizable SPDT latching control switch crafted for superior performance.

Standard 16mm mounting hole combined with a classic 16F flat-head press interface + dual soft LED illumination with power symbol and ring + SPDT (1NO1NC) circuit architecture + high-protection metal body , with the following core advantages:

• Dual illumination indication with power symbol and ringThe press surface is engraved with the internationally standard power icon (Power Icon) and integrated with an outer illuminated ring, providing intuitive and clear human-machine interaction, allowing instant identification of power on/off status with excellent visual quality.
• 16F flat-head minimalist design with refined texture: The all-metal press interface is flat and smooth, offering a stable and crisp tactile feel, fitting flush with the panel to prevent dust accumulation, and delivering exceptional high-end industrial aesthetics with strong resistance to physical impact.
• 16mm standard industrial opening with premium metal housing: Precision 16mm thread pitch, compatible with mainstream panel hole diameters, paired with a stainless steel or nickel-plated brass housing for corrosion resistance and wear durability.
• SPDT (1NO1NC / 5-Pin) precise controlThe switch base is equipped with 5-pin quick-connect/solder terminals (1 common C + 1 normally open NO + 1 normally closed NC + 2 LED pins), offering a compact structure with clear and efficient circuit wiring.
• Latching action mode (Latching / Self-locking): Press the button to latch on and light up the power indicator; press again to unlock and reset, turning it off. It is ideal for use as a system main power switch and an operating mode latch switch.
• IP67 waterproof and dustproof with IK10 impact and shock resistance: The head is equipped with a high-elasticity rubber-plastic sealing ring, which, after secure installation, effectively blocks water, oil, and dust ingress, easily withstanding outdoor rain, snow, and high-dust industrial environments.

[Core Value and Procurement Decision Factors for Different Customer Segments]

1. For Electrical and Hardware Engineers: Standard Power Icon with Flexible 1NO1NC Wiring

The power symbol provides a natural on/off semantic indication, eliminating the need for additional silkscreen panel labeling; the 5-pin layout (including an independent lamp pin and a single set of normally open/normally closed contacts) allows flexible design for always-on mode or synchronized illumination when the device starts up.

2. For equipment assembly and production process engineers: Threaded sleeve fastening, supporting pin and soldering connections

Installed with a metal nut for reinforcement, offering excellent anti-loosening performance; the terminal surface is silver-plated for smooth soldering, and it also supports mating with a dedicated 5-pin quick-connect wire harness socket, improving on-site assembly efficiency.

3. To B2B Procurement and Supply Chain Managers: Source factory quality assurance, complete certifications, and worry-free delivery

Produced on mature automated production lines at Dongguan Shinyear Electronics, with 100% testing for electrical continuity, tactile feel, and waterproof sealing. Large quantities are available in stock, ensuring fast sampling and efficient delivery.
