[Product Overview] 19mm opening diameter 19F high-profile ring illuminated momentary reset metal push button switch (SPDT 1NO1NC / 5-pin terminal / stainless steel or nickel-plated brass housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)

19F High-Profile Ring Illuminated Momentary Reset Metal Push Button Switch (Metal Push Button Switch 19mm High Cap / Illuminated Momentary Switch 1NO1NC) is a product specifically designed for Industrial automation panels, control cabinets, high-end medical equipment, power instrumentation, rail transit, and glove-wearing working environments A high-reliability SPDT momentary control metal switch crafted to perfection.

Standard 19mm mounting hole combined with classic 19F convex/high-profile pressing surface + SPDT (1NO1NC) circuit architecture + ring LED soft illumination + high-protection metal body , with the following core advantages:

• 19F High-Profile/Convex Pressing Surface: Compared to flat-head switches, the high-profile design protrudes more prominently on the panel, offering excellent recognizability, and is extremely suitable for glove operation or blind positioning in low-light environments, with clear force feedback when pressed.
• 19mm standard industrial opening with high-quality metal housing: Precision 19mm thread pitch, compatible with mainstream panel mounting holes, paired with stainless steel or nickel-plated brass housing, corrosion-resistant and wear-resistant, delivering a premium industrial texture.
• 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.
• Momentary / Self-reset Action Mode: Press the button to trigger conduction/signal switching; release it and the actuator immediately springs back to reset automatically. Commonly used for equipment jog operation, pulse signal triggering, Reset emergency reset, and access control triggering.
• 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. To Electrical and Hardware Engineers: 19F convex head with agile pressing, 1NO1NC with fast momentary response

The tall head structure provides excellent physical feedback and pressing feel, making it ideal as a pulse trigger and jog control interface; the 5-pin standard layout (including independent lamp pin and a single set of normally open/normally closed contacts) offers ample wiring space, facilitating quick installation and troubleshooting.

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

Reinforced mounting with metal nuts ensures good anti-loosening performance; the terminal surfaces are silver-plated for smooth soldering, and they also support dedicated quick-connect plug-in cable sockets, 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.
