[Product Overview] 19mm opening diameter 19C flat head ring illuminated latching metal push button switch (SPDT 1NO1NC / 5-pin terminal / stainless steel/brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)

19C flat head ring illuminated latching SPDT metal push button switch (Metal Push Button Switch 19mm Flat Cap / Illuminated SPDT Switch 1NO1NC) is a product specifically designed for Industrial automation panels, control cabinets, power equipment, access control systems, and high-end medical instruments A high-reliability SPDT self-locking control metal switch engineered for demanding applications.

Standard 19mm mounting hole combined with classic 19C flat head press interface + SPDT (1NO1NC) circuit architecture + ring LED soft illumination + high-protection-grade metal body , with the following core advantages:

• 19C flat head refined steel texture design: 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.
• 19mm standard industrial opening with high-quality metal housingPrecision 19mm thread pitch, compatible with mainstream panel hole diameters, paired with a Stainless Steel or Nickel-Plated Brass housing, corrosion-resistant and wear-resistant.
• 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.
• Ring-shaped glowing LED indicator ring (bright and soft, multi-color / wide voltage optional): Uses high-quality LED chips, with uniform glow that is not harsh on the eyes. Available in red, green, blue, yellow, white, and other glow colors, and supports different voltage inputs such as 3V/6V/12V/24V/110V/220V.
• Latching action mode (Latching / Self-locking): Press the button to lock it on and light up the LED; press again to unlock and reset, turning off the light. Commonly used for main power control of equipment, status retention, and mode locking.
• 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 1NO1NC wiring, ring LED with independent pin design

The SPDT 5-pin structure provides clear wiring, supporting independent LED power supply or synchronized illumination following the switch's NO/NC contacts, accommodating diverse circuit logic design requirements.

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

Uses a metal nut for reinforced installation with good anti-loosening performance; the terminal surface is silver-plated for smooth soldering, and also supports mating with a dedicated 5-pin quick-connect wire harness socket, greatly 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.
