Unmatched Durability and High-Current Performance — 16mm 15A Metal Push Button Switch
When precision control meets high current capacity, you get the 16mm 15A metal push button switch — a rugged, compact solution engineered for demanding applications. Built with a robust stainless steel or nickel-plated brass body, this switch combines a sleek industrial look with electrical ratings that set it apart from standard miniature push buttons. The 16mm panel cutout makes it easy to integrate into control panels, automotive dashboards, industrial machinery, marine equipment, and custom DIY projects where reliability is non-negotiable. Rated for 15A at 125/250VAC, it handles substantial loads without hesitation, eliminating the need for relays in many circuits.

Robust Illuminated Options
The integrated LED ring or dot illumination provides clear status indication even in direct sunlight or dim environments. You can choose between a ring-style light pattern on the outer edge of the actuator or a dot-style central light. The LED circuit is completely isolated from the switch contacts, with its own dedicated terminals, allowing you to wire the light independently. Voltage options cover low-voltage DC (6V, 12V, 24V) for automotive and battery-powered systems, as well as high-voltage AC (110V, 220V) designs with built-in resistors for direct connection to mains voltage. This flexibility eliminates external components and simplifies wiring. Dual-color versions (e.g., red/green) change indication when the switch is pressed, perfect for start/stop controls or status toggling.
Typical Applications
Installation Simplicity
The 16mm diameter design fits standard panel knockouts with minimal clearance behind the panel. A jam nut and a waterproof O-ring are included with every switch, making mounting fast and reliable. The screw terminals or quick-connect tabs accept standard wire ferrules or ring/fork lugs for secure connections. For illuminated models, a separate pair of terminals (often marked “+” and “-” for DC or “L1” “L2” for AC) power the LED. The switch body is compact — typically less than 45mm in total depth — allowing installation in shallow spaces. Panel thicknesses from thin sheet metal up to 6mm can be accommodated, giving you versatility across enclosure designs.
Built to Last in Harsh Conditions
The full metal construction and IP65 rating ensure reliable performance when exposed to dust, moisture, and temperature extremes. The contacts are silver alloy, providing low resistance and excellent arc suppression for inductive loads such as motors and solenoids. The mechanical structure uses a self-cleaning sliding contact design that withstands vibration and shock. Every batch undergoes rigorous testing for dielectric strength, insulation resistance, and endurance — ensuring your 16mm 15A metal push button switch delivers consistent operation year after year. Whether you are retrofitting an old machine or designing a new product, this switch offers the perfect balance of form, function, and longevity.
