Product Overview
The KPB22 Series is a Φ22 mm illuminated pushbutton switch that perfectly blends metallic aesthetics with the practicality of plastic, built around the core product philosophy of "metal appearance, plastic core, and customizable illumination." Featuring advanced surface‑treatment processes, the switch delivers a realistic metallic visual effect on a plastic housing – satisfying designers' pursuit of a premium metal look while retaining the inherent advantages of plastic in terms of cost, weight, and ease of processing. The entire series comes standard with translucent pushbutton caps, supporting a variety of cap colors and customizable LED lighting effects. Combined with an IP65 protection rating and dual TUV/ENEC certifications, the KPB22 series offers a cost‑effective, high‑performance human‑machine interface solution that combines aesthetics, reliability, and regulatory compliance – ideal for communication equipment, industrial control, automation systems, consumer electronics, and beyond.
Technical Parameters
Key Features
1. Metal‑Look Plastic Housing – Aesthetics and Cost Efficiency Combined：
Through precision surface coating or electroplating processes, the PC plastic bezel achieves a matte or brushed finish that rivals metal. This innovation delivers three key benefits:
Premium Visual Appeal: The metallic look elevates the overall equipment quality, meeting end‑user expectations for "industrial aesthetics."
Cost‑Effective: The plastic substrate significantly reduces material and processing costs, making the metallic look accessible without the premium price.
Lightweight: Up to 30% lighter than all‑metal switches – particularly suitable for portable devices and aerospace applications.
For applications where anti‑vandal protection is not required, the KPB22 series offers an ideal cost‑effective alternative to metal pushbuttons, striking a clever balance of "looks like metal, performs like plastic."
2. Dual‑Diameter Compatibility – Flexible Installation Without Boundaries：
Supports both Φ22 mm and Φ16 mm panel cutout sizes, enabling seamless switch migration across different equipment generations or product lines:
Φ22 mm Standard Version: Suited for traditional industrial panels, large control cabinets, and applications requiring a prominent operating target.
Φ16 mm Compact Version: Suited for portable equipment, high‑density panels, and space‑constrained embedded systems.
One product family covering two mounting sizes greatly simplifies supply chain management and reduces inventory risk.
3. One Million Mechanical Cycles – Long‑Lasting Durability in High‑Frequency Scenarios：
Momentary Type: 1,000,000 mechanical cycles
Latching Type: 500,000 mechanical cycles
In high‑frequency applications such as automated production lines and communication base stations – where switches are triggered hundreds of times per day – the KPB22 series significantly reduces maintenance costs and downtime with its extended service life.
4. Customizable Multi‑Color Illumination – Richer Status Expression：
The translucent PC button cap is available in a variety of colors, and paired with single‑color, bi‑color, or full‑color LED options, the switch becomes a "lighting window" for equipment status communication:
Single‑Color Options: Red (stop/alarm), green (running/normal), blue (standby/communication), and other standard colors.
Bi‑Color Options: Switches between two colors to indicate different states (e.g., standby‑blue / running‑green).
Ring‑Light Option: A uniformly glowing ring around the perimeter enhances visibility in low‑light environments and adds a modern technological feel.
The free combination of lighting effects and cap colors gives each device a unique visual identity.
5. TUV + ENEC Dual Certification – Global Acceptance：
Certified with both TUV safety approval and ENEC European standard certification, meeting the market access requirements of the EU and major global markets. The IP65 protection rating ensures complete isolation from dust and low‑pressure water jets, keeping the KPB22 series stable and reliable in outdoor communication cabinets, industrial wash‑down environments, and high‑humidity workshops.
Application
Communication Equipment：
Base station RRU maintenance panels, fiber optic distribution frame function keys, and network switch reset buttons – IP65 protection suits outdoor cabinet environments.
Wireless Equipment：
IoT gateway configuration keys, Bluetooth/WiFi module test buttons, and wireless sensor node wake‑up switches – the metallic appearance enhances product aesthetics.
Electronic Measuring Instruments：
Oscilloscope trigger keys, multimeter function selection, and spectrum analyzer mode switching – bi‑color LEDs intuitively display measurement status.
Automation Equipment：
Manual teach buttons on robotic arms, function triggers on AGVs, and mode switching on automated sorting systems – the million‑cycle life matches high‑frequency production lines.
Office Equipment：
Printer function keys, copier mode selection, and projector control panels – the Φ16 mm compact version fits slim‑form‑factor office devices.
Industrial Control Instruments：
PLC control cabinet start/stop buttons, frequency converter parameter confirmation keys, and HMI panel function keys – TUV/ENEC certification meets European market access requirements.
