The development of this switch primarily stems from the industry's urgent demand for highly protective

1.Essential for Outdoor and Humid Environments

Traditional tactile switches lack waterproofing, making them prone to failure in humid/dusty settings like car washes, outdoor lighting, and power tools. This necessitated the creation of waterproof switches with IP67 protection.

2.Miniaturization and Standardization Trends

The 8×8mm form factor is the mainstream installation size for consumer electronics and industrial equipment. The 2-pin (2P) design simplifies wiring, meeting compact space requirements while reducing production and maintenance costs.

3.Import Substitution and Cost Optimization

Overseas brands offer waterproof switches at high prices and long lead times. This domestically produced, cost-effective solution directly replaces comparable imported products, helping enterprises reduce supply chain risks and costs.

4.Reliability Requirements for Automotive Electronics

Interior/exterior vehicle buttons (e.g., wiper/window controls) must operate reliably under vibration and extreme temperature conditions. The IP67 waterproof rating and high mechanical endurance (over 1 million cycles) are engineered to meet these demanding specifications.
