HK-04G-L Dustproof 5A Egg Beater Miniature Micro Switch

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 Tongda HK‑04G‑L micro switch has been further optimized in terms of structure, materials, and precision. It offers higher consistency in switch operation, stronger vibration resistance, and more stable service life. It meets multiple safety certification requirements, making it suitable for large-scale production, foreign trade export, and after-sales maintenance, providing long-term reliable control and protection for equipment.

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).
