When it comes to industrial control systems, durability, precision, and safety are non-negotiable. The 22mm metal push button switch has emerged as a standard in the industry—offering a compact design, rugged construction, and versatile electrical performance. Whether you’re designing control panels for heavy machinery or automation systems, this switch delivers reliability under pressure.
Key Technical Specifications
The SCJ22B Series from Wuhan Sukejie Intelligent Technology is a prime example of a high-performance 22mm switch. Below are its core specifications:
Mounting Hole Diameter: 22 mm (fits standard 22.2 x 22.2 mm panel cutouts)
Housing Material Options: SUS304 stainless steel, brass nickel-plated, or anodized aluminum
Contact Configuration: Available in 1NO1NC or 2NO2NC
Rated Heating Current: AC-15 / DC-13 up to 5A
Switching Voltage: 1.5V to 250V AC/DC
Electrical Life: >500,000 cycles
Waterproof Rating: IP67 (front panel)
Operating Temperature: -30°C to +85°C
These specs make the switch suitable for a wide range of environments—from clean manufacturing floors to outdoor installations exposed to moisture and dust.
Built to Last: Materials and Construction
The choice of materials directly impacts the longevity and performance of a push button switch. The SCJ22B series offers:
Housing: SUS304 stainless steel or brass nickel-plated for corrosion resistance
Key Material: PC + SUS316 stainless steel for impact resistance and aesthetic appeal
Contacts: Silver tin oxide alloy for low resistance and high durability
Base Material: Modified PA66 nylon, known for its thermal and mechanical stability
This combination ensures the switch can withstand mechanical stress, electrical arcing, and environmental exposure.
Electrical Performance You Can Rely On
Industrial switches must handle a variety of loads. The SCJ22B supports:
Inductive loads:
DC-13: 12V / 24V @ 5A
AC-15: 110V / 250V @ 5A
Lamp bead voltage options: 3.3V to 220V AC/DC
Lamp bead current: 2mA to 20mA
Dielectric strength: 2500VAC between pins and housing
Insulation resistance: >100MΩ at 500VDC
These ratings ensure compatibility with both low-voltage signal circuits and higher-power control circuits.
Versatile Operation and Customization
Operational flexibility is another reason the 22mm format is so popular. The SCJ22B series offers:
Working Modes: Self-locking or self-resetting (momentary)
Button Stroke: 3mm total travel, with 1.5mm contact stroke
Actuation Force: ~2.54N
Glowing Colors: Red, green, yellow, blue, white—with RGB or multi-color options available on request
LED Voltage Options: AC/DC from 3.3V to 220V
This makes it easy to integrate into visual indicator systems and control logic without additional components.
Pin Configuration and Wiring
The switch features 2.8 x 0.5 mm pin terminals for both the switch and LED contacts, ensuring secure and straightforward wiring. The pin-style design is compatible with standard connectors and simplifies assembly in high-volume production environments.
