Product Overview

HOSONG 19mm annular power illuminated push button is a dedicated power control key for medium-sized high-end intelligent equipment, matching the mainstream industry-standard Φ19mm precision mounting hole. It is specially developed for precision testing instruments, new energy energy storage systems and intelligent industrial control all-in-one units. Adopting a dual-light structure with soft outer annular illumination plus a central power symbol backlight, it delivers clear light layering to accurately distinguish equipment standby and operating states, effectively lowering risks of erroneous power operation on precision machinery. Equipped with built-in 1NO1NC composite contacts, it supports both momentary and latching operation modes, with multi-color lighting options covering the full voltage range from 3V to 220V, compatible with high and low voltage precision electric control equipment. The whole unit adopts a high-precision sealed metal housing, achieving IP67 waterproof & dustproof rating and IK10 impact resistance. Compact in size, high in assembly precision and exquisite in appearance, it serves as a standard core component for power control on mid-to-high end precision intelligent devices.

4. Manufactured with high-precision assembly craftsmanship, the button delivers crisp, consistent pressing feedback with no jamming or looseness, meeting stringent quality requirements of precision machinery.
5. Miniature sealed structure provides water resistance, dust resistance and anti-interference performance, suitable for laboratories, clean workshops and general industrial working environments.

Application Scenarios

Main power control keys for medium commercial & industrial energy storage all-in-one units and wall-mounted energy storage power supplies; Main power switches for precision testing instruments and laboratory analytical equipment; Power control components for small & medium intelligent industrial all-in-one controllers and embedded industrial control devices; Operation panels for small lithium battery formation and testing equipment in the new energy industry; Power buttons for export-oriented medium-sized automation equipment and customized precision non-standard machinery; Precision control units for small & medium electrical control devices and logistics sorting equipment used in intelligent warehousing systems.

FAQ

Q1: Can the 19mm power button replace standard 22mm buttons directly? A: They have different mounting hole dimensions and are not interchangeable. This model is exclusively designed for Φ19mm precision panels and tailored for small-to-medium high-end precision equipment.

Q2: Does the small-sized dual-light design suffer insufficient brightness? A: Equipped with high-brightness uniform light beads and a miniature light guide structure, it provides sufficient, even illumination that fully meets visibility requirements of precision equipment.

Q3: Can it be customized exclusively for 24V low-voltage precision equipment? A: Custom fixed voltages and exclusive lamp colors are available for bulk orders, to match standardized design schemes of various precision electric control systems.

Customer Case

A precision intelligent equipment enterprise based in Shenzhen specializes in small and medium precision testing and energy storage devices. Its products feature compact, refined panels where conventional larger-size buttons show poor compatibility. After adopting HOSONG 19mm annular power illuminated push buttons, the equipment panel layout becomes neater and more premium, with accurate, clear power status indication and noticeably reduced equipment failure rates. The company places a stable annual order of 13,000 pieces and specifies this button as the standard power key across its full line of precision products.
