Product Overview
The 7A Series is a fully sealed, waterproof upgrade developed by Taclex Switch based on the classic 7M platform. It fully inherits the market-proven electrical performance and extensive range of specifications from the 7M Series, while raising the protection rating to the IP67 fully sealed standard through innovative sealing design and advancements in materials and manufacturing processes. The product features a snap-acting mechanism, allowing contacts to switch on and off instantaneously. This effectively suppresses arc erosion and ensures that every operation is precise, crisp, and reliable. Whether for outdoor equipment exposed to torrential rain or industrial settings subject to high-pressure water jets, the 7A Series safeguards the safe operation of internal circuits with its rock-solid sealing performance.

Key Features
1. Upgraded Classic Platform, Inheriting the Same Performance:
Developed based on the proven 7M series architecture, it fully retains its electrical performance and specification diversity. It can be directly substituted and upgraded without the need to revalidate basic parameters, reducing R&D costs and implementation risks.
2. IP67 Fully Sealed Protection, Withstands Extreme Environments:
Thanks to a combination of precision sealing structures and weather-resistant materials, it offers complete dust protection and protection against brief immersion in water. Dust, rain, water mist, and high-pressure water jets cannot penetrate, making it suitable for the most demanding industrial and outdoor applications.
3. Snap-Acting Mechanism, Millisecond-Level Precision Response:
Utilizing Snap-Acting technology, the contacts switch instantly at the critical point with no intermediate ambiguous states. The operation feels crisp and precise, and the electrical lifespan is extended, making it particularly suitable for high-frequency, high-reliability control circuits.
4. Dual Angles and Dual Directions for Flexible Layout:
Supports two mounting angles—90° and 180°—combined with two actuation orientations—vertical (Straight) and horizontal (Horizontal). Whether for front-panel mounting, side-mounted recessed layouts, or angled operation in confined spaces, you can always find the optimal solution.
