Product Overview

HOSONG 30mm flat non-illuminated metal push button is an extra-large-aperture heavy-duty industrial control switch, designed for customized panels of heavy machinery, large electric control cabinets and engineering equipment with standard Φ30mm mounting hole. Adopting a minimalist non-illuminated sealed structure without light components, it features simplified internal circuits and ultra-low failure rate. Equipped with high-performance 1NO1NC silver alloy composite contacts, it supports momentary jog and latching hold dual operation modes with a rated load of 3A. The thickened stainless steel and chrome-plated brass housing with integrated sealing technology achieves IP67 waterproof and IK10 top-level impact resistance, delivering excellent vibration resistance, wear resistance and oil corrosion resistance, serving as a highly reliable core component for basic start-stop, reset and jog control of heavy-duty equipment.

Product Advantages

1. Extra-large 30mm flat pressing surface with moderate stroke and stable hand feel supports gloved operation and completely avoids misoperation; 2. Minimalist non-light structure has no vulnerable lamp beads or circuits, ensuring extreme stability in dusty, oily and high-low temperature environments; 3. Thickened silver alloy contacts provide stable switching performance and strong arc ablation resistance for frequent equipment start-stop operation; 4. High-strength metal housing resists impact and deformation against long-term vibration and collision of heavy machinery; 5. Fully enclosed waterproof and dustproof structure adapts to outdoor sunlight, rain and workshop oil mist, suitable for all industrial working conditions.

Application Scenarios

Start-stop keys for control panels of large engineering machinery and mining tunneling equipment; manual control switches for high-power electric control cabinets and centralized power distribution equipment; reset and jog control for heavy assembly lines and vehicle automation equipment; heavy-duty electric control equipment supporting outdoor wind power and photovoltaic systems; main control panels of large air compressors, hydraulic pump stations and booster units; basic control keys for port heavy logistics sorting and large conveying equipment.

FAQ

Q1: Can 30mm buttons replace 22/25mm models? A: Non-universal mounting hole size. It is exclusively designed for standard Φ30mm customized panels for heavy large-scale equipment with higher operation safety.

Q2: Will the non-illuminated structure cause water ingress and short circuit after long-term use? A: The integrated full-area sealing structure has no light-transmitting gaps, with better waterproof performance than illuminated models, completely preventing water ingress and short circuit.

Q3: Is extended thread customization available for thick panels? A: Bulk orders support customized extended threads and special contact specifications to fit various thick industrial equipment panels.

Customer Case

A large engineering machinery manufacturer in Shandong specializes in mining and heavy-duty engineering equipment, which operates under severe vibration and heavy dust conditions, leading to frequent failures and misoperation of small-size ordinary buttons. After bulk adoption of HOSONG 30mm flat non-illuminated buttons, the equipment button failure rate dropped by 90% with greatly improved operation safety. The annual stable purchase volume reaches 15,000 pieces as the standard configuration for all heavy-duty equipment.
