Product Description

WEIPENG® is a leading High-Temperature Resistant Micro Switch with Lead Wires manufacturers, suppliers and exporter.

Micro Switch Introduction

The Yueqing Tongda leaded high-temperature micro switch is a precision control component specifically designed for harsh high-temperature environments. Building on the advantages of the HK-14 series short-lever quick-action structure, it features an upgraded lead connection design and full-component high-temperature resistance, allowing stable operation in extreme temperature ranges of -40℃ to 150℃. With its core characteristics of 'high-temperature reliability, strong lead adaptability, and high-precision operation,' the product has become a key control solution for industrial heating equipment, automotive engine compartments, high-temperature home appliances, and other scenarios, providing fundamental assurance for the safe operation of equipment in hot environments.

Founded in 1985, Yueqing Tongda, leveraging over 30 years of experience in industrial control switch development, equips this series of products with a 100,000-level cleanroom and a high-temperature aging testing laboratory. Each batch of products must pass continuous operation testing at 150°C for 72 hours and 5,000 operation cycle tests before leaving the factory. As a partner supplier to brands such as LG and Whirlpool, the company can provide customized services including lead length, terminal type, and arm structure, and offers a 2-year warranty along with localized technical support to ensure perfect compatibility with customers' high-temperature equipment.
