Product Overview

The 19mm conventional ring power illuminated push button is a universal industrial metal control switch with a standard 19mm mounting hole. Adopting a 360° surround ring LED light design, it realizes all-round visual status indication without blind spots. Made of high-quality nickel-plated brass with integrated sealing technology, it features excellent dustproof, waterproof and wear-resistant performance. Built-in constant-current voltage-stabilized LED module effectively avoids light flicker and attenuation caused by industrial voltage fluctuation. Supporting momentary and latching dual modes, it is widely compatible with civil, commercial and general industrial electrical control equipment, serving as a mainstream standard power switch for small and medium automated devices and control cabinets.
