Product Description

WEIPENG® is a leading HK-04G-L Dustproof Micro Switch with Replaceable Limit Function and Self-Reset manufacturers, suppliers and exporter.

Micro Switch Introduction

This model carries diversified current ratings covering 5A and 10A, compatible with AC 125V/250V and DC 12V/24V circuits. Built with anti-arc silver alloy contacts, it maintains low initial contact resistance and stable conduction. With wide working temperature from -25℃ to 125℃ and IP40 dustproof protection grade, it adapts to mild industrial and indoor appliance environments steadily. Its compact dimension at 19.8×10.6×6.4mm realizes space-saving PCB mounting on tight circuit boards.

Yueqing Tongda provides full-series HK-04G-L variants with customizable lever shapes, terminal types and lead configurations. All products pass UL, CSA, VDE, ENEC and CE global safety certifications. Optimized for stable batch supply and easy PCB soldering, it perfectly matches customized small-electronics component sourcing needs with balanced cost and durability.

Micro Switch Application

Micro switches are widely used and reliable in performance, mainly applied in:

- Household appliances: refrigerator lights, microwave oven door locks, washing machine lid switches, and toaster timers.

- Industrial equipment: heavy-duty models suitable for conveyor belts, machinery, and control panels (dustproof and moisture-proof).

- Automotive field: windshield wipers, door-ajar indicators — capable of withstanding vibration and extreme temperatures.

- Electronic devices: miniature switches for remote controls and game controllers (responsive and long-lasting).
