[Product Overview] 16mm opening diameter 16A spherical screw-terminal momentary self-reset metal push button switch (single contact 1NO normally open / 2-pin screw clamp terminal / stainless steel/brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)
16A spherical screw-terminal self-reset metal push button switch (Metal Push Button Switch 16mm Domed Cap / Screw Terminal Momentary Switch 1NO) is a product specifically designed for On-site quick wiring, electrical construction, outdoor access control bells, industrial control panels, and field equipment requiring a minimalist no-light design A highly practical metal control switch crafted for you.
Standard 16mm mounting hole combined with a classic 16A spherical (domed) pressing surface + screw clamp fastening terminal + 1NO normally open circuit + high-protection-grade metal body , with the following core advantages:
- 16A full spherical (domed) surface ergonomic design: The actuator features a smooth rounded domed shape, offering not only elegant visual lines but also excellent finger contact area and lateral pressing force tolerance, ensuring smooth operation without sticking.
- 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: reliable screw wiring, minimalist structure eliminating light-emitting circuits
Adopting a purely mechanical strong-contact 1NO structure, free from LED circuit interference, with strong surge resistance; the screw terminal provides secure and reliable clamping 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.
