Product Description

WEIPENG® is a leading HK-04G-L Dustproof 5A 2-Pin Normally Closed Reset Micro Switch manufacturer, supplier and exporter.

Micro Switch Introduction

The HK-04G-L is a high-precision snap-action micro switch with a lever handle. It is a general-purpose fundamental precision control component with a compact and small structure. Its internal mechanical design is mature, providing stable spring-loaded on-off performance. It is widely used in various small household appliances, smart devices, industrial limit controls, kitchen and bathroom appliances, as well as automation equipment. The switch features a standard three-pin single-pole double-throw circuit, capable of supporting both normally open and normally closed circuits simultaneously. It can flexibly meet various control requirements such as device door detection, travel limits, safety interlocks, and position signal feedback, offering strong versatility and high compatibility for replacement.

Product Features

Compact Structure: Small size (approximately 20 x 10 x 6mm), easy for integrated installation

Fast Action: Uses a snap-action mechanism, small contact spacing, quick response

Various Actuators: Can be equipped with roller levers, spring levers, and other drive forms

Long Life: Mechanical life can reach over 100,000 cycles, high reliability

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).
