16mm Flat Head Metal Push Button Switch (16mm Opening/16A Flat Head/Screw Terminal Wiring/1NO Normally Open Contact/Momentary Self-Reset/Waterproof & Explosion-Proof)
16mm opening mounting thread | 16A flush/flat-head press interface | Stainless steel/nickel-plated rugged housing | 2-pin screw terminal (no soldering required) | Single contact normally open (1NO) | Momentary self-resetting action | IP67 waterproof and dustproof/explosion-proof impact resistance | Free samples and CAD drawings available
This 16A flat head screw terminal self-reset metal push button switch features an industrial-grade practical design with "all-metal rugged housing + 16mm standard mounting hole thread + 16A flat flush press surface + screw clamp terminals (2-pin, no light) + 1NO normally open contact + waterproof sealed structure." The actuator adopts a flat flush design that sits smoothly against the panel after installation, effectively preventing accidental actuation while maintaining a clean visual appearance. The tail is equipped with 2-pin screw clamp terminals, allowing quick wire connection with a screwdriver without soldering, significantly reducing the threshold for on-site installation and maintenance. It features momentary self-reset operation (press to close/release to automatically spring back and open), and the housing offers IP67 waterproof and dustproof protection along with IK10 explosion-proof impact resistance, easily handling outdoor exposure to weather and harsh industrial environments. 2D/3D drawings and free sample requests are available.

【Product Overview】16mm opening diameter 16A flat head screw terminal momentary self-reset metal push button switch (single contact 1NO normally open / 2-pin screw clamp terminals / stainless steel/brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)
16A Flat Head Screw Terminal Self-Reset Metal Push Button Switch (Metal Push Button Switch 16mm Flat Cap / Screw Terminal Momentary Switch 1NO) is a product specifically designed for Applications for on-site quick wiring, electrical installation, outdoor access control systems, industrial control panels, and equipment requiring anti-accidental-actuation flush designs A highly practical metal control switch crafted for you.
Standard 16mm mounting hole combined with a classic 16A flat flush press surface + screw clamp fastening terminals + 1NO normally open circuit + high-protection-grade metal body , with the following core advantages:
- 16A Flat Head anti-accidental-actuation design: The actuator features a flat flush shape, providing a neat and aesthetically pleasing appearance after panel installation with clean lines, effectively reducing false operations caused by accidental bumps or scrapes.
- 2-pin screw lock terminal (solder-free quick installation): The tail adopts a screw-locking structure, allowing cables to be quickly secured with an ordinary screwdriver, eliminating reliance on on-site soldering tools and greatly enhancing installation efficiency and after-sales maintenance convenience.
- 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.
- 1NO normally open contact for precise control: Simple and reliable structure—circuit is open when not pressed, closes and conducts when pressed, and instantly springs back to open upon release.
- Momentary / self-reset actuation mode: Press to conduct, release to reset; commonly used for momentary triggering, signal pulsing, start pulses, and access control chime operations.
- 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: flat flush panel mounting, screw terminal wiring is reliable and vibration-resistant
The flush panel design saves space and prevents accidental actuation; the pure mechanical high-contact-force 1NO structure has no illumination circuit interference, and the screw clamp terminals are securely fastened with outstanding resistance to vibration-induced loosening.
2. To on-site installation and maintenance engineers: on-site soldering-free, ultra-fast wire locking and power-on
Say goodbye to soldering iron work, especially suitable for on-site field construction, secondary modification of control boxes, or environments without soldering conditions, greatly shortening construction time.
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.
