Product Description

WEIPENG® is a leading Silver Contact Water Heater High-Sensitivity Lever Micro Switch manufacturers, suppliers and exporter.

Micro Switch Introduction

Relying on the company's over thirty years of experience in spring contact design, the HK-14 series uses high-elasticity beryllium copper contacts, processed through 12 precise stamping and heat treatment procedures, with an elasticity decay rate of ≤3% (the industry average is 8%). It achieves outstanding performance with a mechanical lifespan of over 1 million operations and an electrical lifespan of 100,000 operations. Calculated at 60 high-frequency operations per day, it can reliably operate for more than 5 years. The core housing is made of UL94 V-0 flame-retardant PA66 reinforced engineering plastic, offering impact resistance, aging resistance, and UV protection, capable of withstanding extreme temperatures from -25°C to 125°C, and it shows no performance degradation after 1000 hours of high and low-temperature cycling tests. The electrical operation frequency can reach 15 times per minute, and the mechanical operation frequency can reach 60 times per minute, making it perfectly suitable for continuous operation scenarios such as industrial automation production lines and high-frequency household appliances.
