[Product Overview] Opening diameter 25mm ring illuminated latching metal button switch (DPDT 2NO2NC / 8-pin terminal / stainless steel/brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)

25mm Ring Illuminated Latching Metal Button Switch (Metal Push Button Switch 25mm / Illuminated Metal Switch 2NO2NC) is a product specifically designed for Industrial automation panels, control cabinets, high-end medical equipment, power instruments, rail transit, and harsh outdoor environments Crafted as a high-reliability dual-circuit linked control metal switch.

The standard 25mm opening design combines installation convenience with excellent operating feel, combined with DPDT (2NO2NC) circuit architecture + ring LED soft illumination + high-protection-grade metal body , with the following core advantages:

• 25mm standard mounting opening and high-quality metal housing: Precision 25mm thread pitch, paired with stainless steel or nickel-plated brass housing, corrosion-resistant, wear-resistant, and exuding premium industrial quality.
• DPDT (2NO2NC / 8 Pin) dual-circuit independent control: The switch base is equipped with 8-pin quick-connect/solder terminals (2 sets of common pins C + 2 sets of normally open NO + 2 sets of normally closed NC + 2 sets of LED lamp pins), enabling synchronized isolated control of live and neutral wires or dual-circuit linked operation.
• 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 latch and maintain conduction while illuminating the LED; press again to unlock and reset to disconnect. Commonly used for equipment power master control and functional state retention.
• 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: 2NO2NC dual-circuit independent/linked control for higher safety

Standard 8-pin layout (including independent lamp pins and two sets of independent normally open and normally closed contacts), capable of simultaneously disconnecting both the neutral and live wires of AC220V (L/N dual break), or simultaneously controlling a high-voltage circuit and a low-voltage signal feedback circuit, significantly enhancing system safety.

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.
