In the vast world of industry, there is a seemingly inconspicuous yet crucial role – the limit switch. It is like a tireless safety “little guardian”, shouldering a “big role” with its “small size”, silently protecting the safety and stability of industrial production.

Limit switches, as a fundamental and crucial electromechanical sensor, play an indispensable role in the fields of automation control and safety protection. 

The AC contactor serves as a vital component in industrial control and power systems, primarily functioning to enable remote automatic control of high-power electrical loads. As an electromagnetically operated switching device, it utilizes low-voltage signals to manage high-voltage, high-current circuits, effectively ensuring operational safety while enhancing system automation.

At this time of flourishing life and vibrant growth, ZNFO Electric Import & Export (Wenzhou) Co., Ltd. was officially established on December 7, 2025! This is not only a new starting point for ZNFO Electric to deeply cultivate the field of international trade, but also an important milestone in building a bridge for Sino-foreign economic and trade cooperation and empowering the global market.

When the module on the moving part hits the LXT series limit switch, its internal mechanical structure drives the contact to move and realize the switching of the circuit, thereby controlling the stroke of the mechanical equipment and performing limit protection.

From September 23rd to 27th, 2025, the 2025 China International Industry Fair (CIIF), themed "New Industrial Quality, Unbounded Intelligent Manufacturing," was grandly held at the National Exhibition and Convention Center (Shanghai).

As one of the most anticipated professional exhibitions under the China International Industry Fair (CIIF), IAS has become a key exchange platform for the global industrial automation sector. IAS 2025, held from September 23rd to 27th at the National Exhibition and Convention Center (Shanghai), is expected to attract hundreds of exhibitors and hundreds of thousands of professional visitors from around the world. ZNFO Co., Ltd. (Hall 1.1, E086) will showcase the most cost-effective and innovative industrial control switches for industrial automation, offering opportunities to win exclusive industry solutions and gain insights into future trends and directions in industrial development.

The core difference between an overspeed switch and a limit switch is that the monitoring objects and functional goals are completely different: the former monitors "rotational speed" to prevent overspeed hazards, while the latter monitors "mechanical position/travel" to control motion boundaries.

To promote communication and integration between new and old members and support the collaborative development of young entrepreneurs, the Chamber of Commerce held a 2025 New Member Meeting on the evening of August 20th, themed "Integrating New Strengths and Drawing a New Chapter Together." The meeting was held in a warm atmosphere, with new and old members gathering together to discuss their entrepreneurial dreams and chart a new development blueprint.
