Product Overview

HOSONG 25mm dual-illuminated power button is a dedicated main power switch for super-large-aperture heavy-duty equipment, matching Φ25mm large industrial panels. Adopting dual visual indication of outer annular running light and central power symbol backlight, it clearly distinguishes equipment standby power-on and running status. Built-in high-stability 1NO1NC composite contacts support momentary and latching dual modes, with full 3V–220V voltage coverage and multi-color lighting options. The thickened sealed metal housing provides IP67 waterproof and IK10 impact resistance with excellent vibration resistance and visibility, serving as the premium main power control key for heavy machinery, outdoor energy storage and large industrial units.

Core Parameters

Product Advantages

1. Independent dual-light indication clearly separates standby and running status to minimize misoperation risks of heavy machinery; 2. Super-large 25mm luminous area ensures clear recognition under strong outdoor light and long-distance operation; 3. Thickened contacts deliver stable conduction and strong arc resistance for frequent power switching of large equipment; 4. Integrated waterproof and dustproof structure adapts to outdoor sunlight, rain, workshop oil and dust environments; 5. Stable heavy pressing feeling fits gloved operation for improved safety and operability.

Application Scenarios

Main power control for large port cranes and mining equipment; overall power switch for outdoor large photovoltaic energy storage units and wind power supporting electric control systems; main power keys for heavy hydraulic units and large air compressor systems; power-on switches for central control cabinets of super-large automated lines; main power panels for large construction machinery and mobile operation equipment; start-stop control for high-power equipment in centralized energy storage power stations.

FAQ

Q1: Can dual lights be set with different logic independently? A: Two independent lighting circuits support separate or synchronous lighting, customizable for standby, running and fault multi-logic control.

Q2: How is the anti-vibration performance of large-size buttons? A: Reinforced integral locking structure and thickened metal housing provide better vibration resistance than conventional 22mm power buttons.

Q3: Are non-standard high/low voltage customizations available? A: Bulk orders support custom special voltage, exclusive lamp color and dual-color combinations to match customized electric control schemes of large equipment.

Customer Case

Customer Case

A Jiangsu new energy heavy industry enterprise specializes in large outdoor photovoltaic energy storage equipment, which features large volume, long operation distance and strong outdoor sunlight, leading to poor visibility of ordinary buttons. After adopting HOSONG 25mm dual-illuminated power buttons, equipment status recognition efficiency and outdoor stability were greatly improved. With an annual purchase of 8,800 pieces, it has become the standard main power button for large energy storage units.
