Product Overview

HOSONG 25mm flat annular illuminated metal push button is a large-aperture industrial control switch tailored for heavy-duty machinery, large cabinets and outdoor industrial equipment. Featuring a super-large Φ25mm mounting hole and wide pressing area, it provides high operation tolerance. Equipped with 1NO1NC silver alloy composite contacts, it supports momentary and latching dual modes. The full-coverage annular soft LED offers multi-color and full voltage compatibility from 3V to 220V. The thickened sealed brass chrome-plated/stainless steel housing achieves IP67 waterproof and IK10 heavy impact resistance, delivering far longer mechanical life than ordinary buttons, ideal for visual control of heavy and outdoor industrial equipment.

Product Advantages

1. Super-large 25mm pressing area ensures stable operation with thick heavy-duty gloves and effectively prevents misoperation; 2. Wider annular luminous area provides clearer status recognition from long distance and under strong light; 3. Full-voltage universal lamp beads reduce inventory pressure and fit both high and low voltage equipment; 4. Thickened metal housing resists impact and deformation, adapting to severe vibration of heavy machinery; 5. Integrated fully sealed structure provides excellent water, oil and dust resistance for long-term outdoor and harsh indoor use.

Application Scenarios

Widely used in gantry machine tools, heavy forging equipment and port crane control panels; outdoor photovoltaic inverter cabinets and large energy storage station main panels; construction machinery and mining auxiliary electric control equipment; central control consoles of large automated production lines and heavy logistics sorting equipment; air compressors and hydraulic unit start-stop control systems.

FAQ

Q1: Can 25mm buttons replace 22mm models directly? A: The mounting hole size is different, direct replacement is unavailable. It is specially designed for customized Φ25mm panels for heavy machinery.

Q2: Is the brightness higher for large-size annular lights? A: Larger luminous area and uniform light distribution deliver wider visual range and better recognition under strong outdoor light.

Q3: Will lamp beads loosen under heavy vibration? A: Adopting locked lamp bead structure and integral potting process, it is anti-vibration and anti-loose without flickering or lamp failure under long-term vibration.

Customer Case

A heavy machinery manufacturer in Foshan specializes in gantry machining centers. The original 22mm buttons caused frequent misoperation with gloved hands and poor visibility outdoors. After switching to HOSONG 25mm flat annular illuminated buttons, operational errors were greatly reduced with clear status display under strong sunlight. The overall equipment grade was upgraded, with an annual stable order of 9,000 pieces as standard configuration for all heavy machine tools.
