Product Overview
HOSONG 25mm flat non-illuminated metal push button is a super-large-aperture heavy-duty industrial basic control switch, specially designed for heavy machinery, outdoor equipment and large units with its wide pressing surface and Φ25mm standard hole. Adopting minimalist non-illuminated sealed structure with fewer internal components and ultra-low failure rate, it is equipped with 1NO1NC composite contacts supporting momentary and latching modes, rated at 3A load. Thickened stainless steel/chrome-plated brass housing and integral sealing technology achieve IP67 waterproof and IK10 impact resistance, featuring excellent oil resistance, wear resistance and vibration resistance, serving as a cost-effective core component for reset, jog and start-stop control of large equipment.

Product Advantages
1. Super-large flat pressing surface ensures accurate and stable operation with heavy gloves to avoid misoperation; 2. Minimalist non-light structure with fewer fault points delivers outstanding stability in dusty, low-temperature and oily environments; 3. Large contact area ensures stable conduction for frequent start-stop control of heavy machinery; 4. Thickened metal housing resists impact and deformation against equipment vibration and collision; 5. High-grade sealing structure adapts to outdoor, humid and dusty heavy-duty working conditions for long service life.
Application Scenarios
Reset and jog control for mining machinery and port cranes; start-stop buttons for outdoor photovoltaic and wind power supporting electric control equipment; control panels of heavy hydraulic units and large air compressors; basic keys for central consoles of super-large automated production lines; manual control switches for construction machinery and mobile operation equipment; auxiliary control loops for large energy storage power stations and centralized distribution cabinets.
FAQ
Q1: Is it suitable for high-frequency jog debugging? A: Large silver alloy contacts resist arc and high-frequency switching damage, ideal for frequent equipment debugging and reset operations.
Q2: Does large size weaken sealing performance? A: Full-area integrated sealing ring matches large panel structure, maintaining consistent IP67 protection level as small-size buttons.
Q3: Can it replace old 25mm generic buttons? A: Universal national standard 25mm hole size and compatible electrical parameters support direct replacement and upgrade without panel or circuit modification.
Customer Case
A Jiangsu heavy machinery enterprise specializing in port cranes faced high failure rate and frequent maintenance of generic buttons under long-term outdoor harsh conditions. After batch replacement with HOSONG 25mm flat non-illuminated buttons, equipment button failure rate dropped by 85% with greatly improved outdoor weather resistance. The annual stable purchase volume reaches 11,000 pieces, effectively reducing after-sales operation and maintenance costs.
