Product Overview

HOSONG 30mm flat annular illuminated push button is an extra-large-aperture visual industrial control switch tailored for large engineering machinery, outdoor energy storage units and heavy-duty automation equipment, matching standard Φ30mm large-hole panels. Equipped with a full-coverage soft annular LED lighting system with uniform light diffusion, it supports 3V–220V full voltage compatibility and multi-color customization to accurately display equipment running, standby and fault status. Built-in high-durability 1NO1NC composite contacts support momentary and latching dual modes for diverse control logic. The thickened sealed metal housing achieves IP67 waterproof and IK10 super impact resistance with excellent vibration and corrosion resistance, serving as the preferred visual control component for large high-end heavy-duty equipment.

Product Advantages

1. Super-large 30mm annular luminous area ensures clear status recognition under strong outdoor light and long-distance operation, far exceeding ordinary-size buttons; 2. Full-voltage universal lamp beads adapt to both high and low voltage industrial equipment and reduce inventory pressure; 3. Soft diffused annular light delivers no glare or flicker, eye-friendly for long-term human-computer interaction; 4. High-durability silver contacts resist arc ablation and frequent switching, adapting to high-frequency operation of large equipment; 5. Integrated sealed structure provides comprehensive water, oil, dust and vibration resistance for complex harsh heavy-duty and outdoor working conditions.

Application Scenarios

Visual control panels for large mining machinery and engineering cranes; heavy-duty electric control equipment for outdoor large energy storage units and photovoltaic inverters; status indication keys for heavy automated production lines and vehicle manufacturing equipment; control switches for large hydraulic units, booster equipment and air compressor systems; operation panels for port heavy conveying and intelligent sorting large equipment; running state control for industrial large constant-temperature and drying units.

FAQ

Q1: Does the 30mm annular light support dual-color switching? A: Bulk customization of dual-color switching function is available, with customizable light colors corresponding to different equipment working states.

Q2: Is the large-size lamp prone to dust ingress and dimming? A: Adopting embedded sealed light guide structure, it completely prevents dust and moisture ingress with no brightness attenuation after long-term use.

Q3: Is it suitable for low-voltage DC equipment? A: Full voltage coverage of 3V, 6V, 12V, 24V, 48V and 220V supports both AC and DC equipment with ultra-high compatibility.

Customer Case

A heavy industry technology enterprise in Xuzhou specializes in large engineering cranes, which operate in strong outdoor sunlight with long operation distances, leading to poor visibility of ordinary buttons. After adopting HOSONG 30mm annular illuminated buttons, equipment status indication becomes clear and intuitive with greatly improved outdoor operation safety. With an annual purchase of 12,000 pieces, it has become the standard visual key for all engineering equipment.
