19mm metal push button switch (19mm opening/19C flat head/DPDT 2NO2NC/ring illuminated LED with light/latching type/waterproof and explosion-proof)
19mm panel mount thread | 19C flat-head metal actuation surface | Stainless steel/nickel-plated rugged housing | 8 Pin 2NO2NC double-pole double-throw independent dual-circuit control | Ring LED indicator (multiple color options) | Latching action mode | IP67 waterproof and dustproof/explosion-proof impact resistant | Free sample requests and CAD drawings
This 19C flat head ring illuminated latching DPDT metal push button switch adopts an industrial-grade precision design featuring a "full metal rugged housing + 19mm standard mounting hole thread + 19C flat head press interface + ring LED illuminated ring + 2NO2NC DPDT circuit + waterproof sealing structure." The switch actuator is equipped with a uniform and elegant ring LED illuminated ring (supporting red/green/blue/yellow/white and wide-voltage customization), providing clear equipment status indication in complex environments; it adopts a DPDT (2NO2NC / 8 pins: including 2 groups of common pins + 2 groups of normally open + 2 groups of normally closed + 2 groups of LED pins) wiring architecture, enabling simultaneous switching of two independent circuits or switching between normally open and normally closed signals (such as simultaneous disconnection of live and neutral wires / synchronized control of dual-channel signals). It features latching function (press once to lock and conduct / press again to reset and disconnect), and the housing offers IP67 waterproof and dustproof protection along with IK10 explosion-proof and impact resistance, easily coping with outdoor wind and rain as well as harsh industrial environments. 2D/3D drawings and free sample requests are available.

【Product Overview】19mm opening diameter 19C flat head ring illuminated latching metal push button switch (DPDT 2NO2NC / 8-pin terminal / stainless steel/brass nickel-plated housing / IP67 waterproof and dustproof / industrial-grade explosion-proof)
19C flat head ring illuminated latching DPDT metal push button switch (Metal Push Button Switch 19mm Flat Cap / Illuminated DPDT Switch 2NO2NC) is a product specifically designed for Industrial automation panels, control cabinets, power equipment, dual-circuit isolation control, and high-end medical instruments A high-reliability DPDT latching control metal switch crafted with excellence.
Standard 19mm mounting hole combined with classic 19C flat head press interface + DPDT (2NO2NC) independent dual circuit + ring LED soft illumination + high-protection-grade metal body , with the following core advantages:
- 19C flat head refined steel texture design: The all-metal press interface is flat and smooth, offering a stable and crisp tactile feel, fitting flush with the panel to prevent dust accumulation, and delivering exceptional high-end industrial aesthetics with strong resistance to physical impact.
- 19mm standard industrial opening with high-quality metal housingPrecision 19mm thread pitch, compatible with mainstream panel hole diameters, paired with a Stainless Steel or Nickel-Plated Brass housing, corrosion-resistant and wear-resistant.
- DPDT (2NO2NC / 8 Pin) dual-circuit independent control: The switch bottom is equipped with 8 Pin quick-connect/solder terminals (2 groups of common pins C1/C2 + 2 groups of normally open NO1/NO2 + 2 groups of normally closed NC1/NC2 + 2 groups of LED pins), enabling synchronized control of two independent circuits (such as simultaneous disconnection of AC L/N live and neutral wires, or synchronized linkage between the main circuit and signal circuit), offering a higher safety level.
- 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 lock and conduct while illuminating the LED; press again to unlock and reset to disconnect. Commonly used for equipment power master control and dual-channel status 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. To Electrical and Hardware Engineers: 2NO2NC independent dual circuits, high-safety isolation design
The double-pole double-throw (8-pin) structure allows the switch to simultaneously control the main power (high voltage) and control circuits (low voltage), or achieve bipolar disconnection of both the live and neutral wires for AC 220V, significantly enhancing the equipment's electrical safety level and meeting high-standard industrial regulations.
2. For equipment assembly and production process engineers: Threaded sleeve fastening, supporting pin and soldering connections
Reinforced installation with metal nuts provides excellent anti-loosening performance; the terminal surfaces are silver-plated for smooth soldering, and they also support matching a dedicated 8-pin quick-connect wiring harness socket, simplifying on-site assembly and maintenance.
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.
