Product Overview

HOSONG 22mm dual-illuminated push button with annular ring & power symbol is specially developed as main power switch for medium & large industrial equipment. The outer annular indicator plus central standard power backlight adopts two-layer lighting logic to distinguish power-on standby and equipment running status clearly, effectively reducing misoperation risk. Designed with standard Φ22mm flat head, 1NO1NC composite contacts and momentary/latching options, it supports full-voltage multi-color lighting. Sealed chrome-plated brass/stainless steel housing meets IP67 waterproof & IK10 impact resistance, ranking as preferred main power key for large machine tools, energy storage systems, charging piles and full-set automation lines.

Core Parameters

Product Advantages

1. Dual-layer indication logic: power symbol shows energized status while annular light reflects running state for safer judgment;
2. Large 22mm pressing surface facilitates operation with thick gloves in heavy workshops, ideal for frequent main power switching;
3. Two independent lighting circuits support customized simultaneous or separate lighting to match electric control logic design;
4. Dual composite contacts collect power status and running signals synchronously for large PLC system programming;
5. Fully sealed dust & waterproof structure resists cutting fluid, dust and humidity for long-term non-stop equipment operation.

Application Scenarios

1. Main power switches for large CNC machine tools, bending machines and forging equipment
2. Main control power keys for commercial & industrial energy storage all-in-one units and high-power PCS converters
3. Overall main power switches for integrated DC charging piles and high-power AC charging piles
4. Power-on main control buttons for central control cabinets of complete automated production lines
5. Power control for large photovoltaic inverters and centralized energy storage power station distribution cabinets
6. Main power panel keys for construction machinery and port heavy conveying equipment

FAQ

Q1: Will latching version stay closed and auto-start after power recovery? A: Built-in power-off auto-reset structure cuts off circuit once power fails, complying with national electrical safety standard without auto-restart after re-energization. Q2: Can two groups of lights be configured with different voltages separately? A: Standard version uses identical voltage for both lights; customized different voltage design for two circuits is available for bulk orders with special control demands. Q3: Are contacts prone to ablation under frequent switching? A: Thickened silver alloy contacts feature strong arc suppression, resisting oxidation and ablation after millions of switching cycles, perfect for frequent power on-off scenarios.

Customer Case

A complete automation system integrator in Foshan undertakes assembly line turnkey projects for auto-parts factories. Previous single-light power buttons caused poor status recognition and frequent accidental power on/off. After switching to HOSONG 22mm dual-illuminated power buttons, operational errors decreased by 90% and electrical failure complaints were greatly reduced. With steady annual order of 27,000 pieces, this button is defined as standard main power switch across all projects.
