Product Overview

HOSONG 22mm flat annular illuminated push button serves as major visual control component for heavy industrial control, matching industry-standard Φ22mm large mounting hole panels. Equipped with flat round head and outer diffused annular LED indicator, it supports red, green, blue, yellow, white, dual-color options with full voltage range 3V~220V. Built-in 1NO1NC composite contacts with momentary/latching options, its sealed chrome-plated brass/stainless steel housing meets IP67 dust/waterproof and IK10 impact resistance. It realizes both equipment operation and real-time status indication, becoming the most popular illuminated control switch for production lines, energy storage systems and charging piles.

2. Start-stop indicator keys for high-power DC charging piles & commercial energy storage cabinets
3. Control panel switches for gantry milling machines, bending machines and heavy forging equipment
4. Operating components for centralized photovoltaic inverters and large PCS cabinets
5. Control panels for port heavy sorting equipment and packaging forming machinery
6. Large on-board rail transit cabinets and fixed main electrical control panels

FAQ

Q1: Does annular light suffer uneven brightness or flicker? A: Built-in constant-current stabilized lamp beads and uniform light guide structure eliminate flicker across full voltage range, with even brightness and no thermal degradation during long-term lighting. Q2: Can dual-color light be controlled to light up single color separately? A: Dual-color version adopts two independent circuits, supporting single-color lighting or simultaneous lighting for customized status logic definition. Q3: What panel thickness is compatible? Can extended thread be customized for thick plates? A: Standard for 1~6mm panels; extended thread customization is available for panels thicker than 6mm without extra adapter nuts.

Customer Case

A charging pile manufacturer in Jiangsu adopts 22mm illuminated start-stop buttons as standard parts for commercial high-power DC chargers. Previous competitive buttons suffered dim light and high water ingress failure rate. After switching to HOSONG 22mm flat annular illuminated buttons, enclosure protection and visibility are greatly improved with rework rate cut by 83%. With annual order of 25,000 pieces, the company successfully qualified as supplier for State Grid system.
