In the world of industrial controls, professional audio equipment, and custom instrumentation, the need for a reliable, visually clear, and electrically robust interface is paramount. The 16mm Metal Push Button Switch with Ring LED emerges as the definitive solution, perfectly balancing high-current switching capability with unmistakable visual status indication. This isn’t just a button; it’s a critical communication node between the operator and the machine.
The Core Problem It Solves
Engineers and designers often face a dilemma: choose a small, aesthetically pleasing switch that can’t handle real power, or install a bulky, high-current switch that ruins the panel design. This 16mm switch shatters that compromise by integrating a 10A high-current rating with a compact, LED-illuminated metal housing, offering both performance and polish.
Engineering Excellence in a 16mm Package
1. High-Current Capacity in a Small Form
Don’t let its size fool you. With a rated heating current (Ith) of 20A and switching capabilities of 10A at 24VDC (DC-13) and 15A at 250VAC (AC-15 for resistive loads), this switch confidently handles demanding circuits for motor starters, power supplies, and industrial solenoids. The secret lies in its silver tin oxide alloy contacts, which resist welding and arcing, ensuring stable performance over its long 30,000+ cycle electrical life.
2. Unmistakable Visual Status with Ring LED
The 360° ring-shaped LED provides clear, omnidirectional status feedback—crucial in low-light environments or from a distance. Compatible with common 5V or 12V DC logic-level power supplies (also available in 3.3V, 24V up to 220V AC/DC), it integrates seamlessly into modern control systems without the need for additional drivers.
3. Built for Demanding Environments
Rugged Construction: The housing, available in SUS304 stainless steel, nickel-plated brass, or anodized aluminum, offers superior corrosion resistance, EMI shielding, and a professional finish.
Environmental Sealing: Standard IP65 rating (dust-tight and protected against water jets) with an optional IP67 upgrade ensures reliable operation in wash-down areas, outdoor panels, or dusty industrial settings.
Wide Operating Range: Functions flawlessly from -30°C to +85°C, making it suitable for applications from freezer controls to equipment near heat sources.
4. Operational Flexibility
Choose between Latching (Self-Locking) and Momentary (Self-Resetting) actions. The latching function is perfect for a main POWER START button or mode selector, while the momentary action is ideal for start/stop, reset, or signal commands.
