16mm spherical metal push button switch (16mm opening/16A domed surface/solder lug terminal/1NO normally open contact/momentary self-reset/waterproof and explosion-proof)
16mm opening mounting thread | 16A curved/spherical pressing interface | Stainless steel/nickel-plated sturdy housing | 2-pin solder lug terminals | Single contact normally open (1NO) | Momentary self-resetting action | IP67 waterproof and dustproof/explosion-proof impact resistant | Free samples and CAD drawings available
This 16A domed solder lug momentary metal push button switch adopts an industrial-grade practical design featuring a "full-metal rugged housing + 16mm standard opening thread + 16A smooth spherical pressing surface + solder lug terminal (2-pin, no light) + 1NO normally open contact + waterproof sealed structure." The actuator features a full, rounded spherical (domed) design, offering a fine and comfortable touch with easy multi-angle pressing; the tail is equipped with a 2-pin easy-solder terminal (with wire-through holes) that ensures smooth solder wetting and firm joints, greatly enhancing wiring stability and vibration resistance inside space-compact control boxes. It provides momentary self-reset function (press to close/release to automatically spring back and open), and the housing delivers IP67 waterproof and dustproof performance along with IK10 explosion-proof and impact resistance, easily handling outdoor exposure to wind and rain as well as harsh industrial environments. 2D/3D drawings and free sample requests are available.

[Product Overview] 16mm opening diameter 16A domed solder lug momentary self-reset metal push button switch (single contact 1NO normally open / 2-pin solder terminal / stainless steel or brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)
16A domed solder lug momentary self-reset metal push button switch (Metal Push Button Switch 16mm Domed Cap / Solder Terminal Momentary Switch 1NO) is a product specifically designed for High-vibration equipment, compact control boxes, access control call systems, industrial control panels, and field devices requiring a minimalist no-light design A high-reliability metal control switch built to exacting standards.
Standard 16mm mounting hole combined with a classic 16A spherical (domed) pressing surface + silver-plated easy-solder 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 with elegant visual lines, offering excellent finger contact area and lateral pressing force tolerance, ensuring smooth operation without sticking.
- 2-pin silver-plated solder terminal (with wire threading hole): The tail adopts a high-conductivity copper alloy silver-plated solder terminal, offering smooth solder wetting and reliable soldering, suitable for pre-soldered cables in control boxes subject to high vibration or space constraints.
- 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: firm soldering for vibration resistance, minimalist circuit for anti-interference
Pure mechanical strong-contact 1NO structure with no light circuit interference; solder terminals provide secure connections that resist loosening on high-vibration machinery or mobile devices, ensuring stable signal transmission.
2. To Production Assembly and Process Engineers: Silver-plated terminals offer easy solder wetting, greatly improving soldering iron efficiency
The terminals are precision silver-plated, allowing fast solder wetting and full, well-formed solder joints. The wire-through hole design effectively prevents wire slippage before soldering, enhancing assembly line efficiency in factories.
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.
