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

19C flat head with power light latching metal button switch (Metal Push Button Switch 19mm 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 19mm mounting hole combined with classic 19C flat head press interface + power symbol LED soft illumination + SPDT (1NO1NC) circuit architecture + high-protection metal body , with the following core advantages:

• Power symbol illuminated indicator: The press surface is engraved with the internationally standard power icon, providing intuitive and clear human-machine interaction, allowing instant recognition of power on/off status with excellent visual quality.
• 19C flat head minimalist 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.
• 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.
