Product Description

WEIPENG® is a leading HK-04G-L Dustproof 5A Dough Kneading Machine Travel Limit Switch Manufacturer, Supplier and Exporter.

Micro Switch Introduction

This switch adopts a single-pole double-throw (SPDT) output structure, supporting both normally open and normally closed circuit modes simultaneously, allowing device manufacturers to flexibly wire it according to control logic. It uses a precision bouncing mechanism internally to ensure that the switch can quickly make or break the circuit with minimal travel and light force, effectively reducing contact arcing and enhancing safety and electrical lifespan. The long lever design provides a smoother trigger action and more even force distribution, making it suitable for indirect triggering, pressing through an intermediary, or long-distance travel detection scenarios, offering more flexible installation positions.

The casing is made of high-temperature-resistant, impact-resistant flame-retardant materials, capable of adapting to temperature changes during device operation, and is not easily deformed, cracked, or aged, maintaining stability even in vibrating environments. The internal contacts are made of high-quality alloy materials, with low contact resistance and stable conductivity, able to withstand frequent switching without contact failure or malfunction, meeting the reliability requirements for long-term continuous use. The pin structure is sturdy, with good solderability, compatible with automated surface-mounting and manual wiring, making installation simple and connections stable.

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).
