Product Description

WEIPENG® is a leading Weipeng Dust-Proof Roller Beater Micro Switch 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.

Equipped with customized thin bent lever actuator, HK-04G-L features ultra-small travel snap-action mechanism. Only slight external pressure triggers rapid circuit commutation, with precise operating stroke and clear reset feedback. 3-pin SPDT circuit structure supports normally open and normally closed dual signal output, flexible for diversified circuit logic. The solid PBT flame-retardant housing resists aging, high temperature and mechanical collision, strengthening internal component protection.

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).
