Snap action, limit switches are used for a wide range of applications. ZV-NJ-2S switches are one type of snap action switches, specifically designed for use in industrial and manufacturing applications.

ZV-NJ-2S snap action switch is made up of an actuator, electrical contacts, an actuator plunger and a housing. The actuator, or operating elements, are designed to move when a certain amount of force is applied or when a minimum or maximum limit is reached. This movement triggers the electrical contacts to open or close. ZV-NJ-2S snap action switches can be used to control the on and off switching of motors, lighting systems, air compressors, industrial fan systems, and more.

When the actuator plunger is moved, it pushes the contacts to make or break an electrical connection. The contacts can be single-pole, double-pole, or multiple-pole, depending on the application. An external spring, called the “snap diaphragm," is used to return the actuator to its original position when the force that triggered it is removed.

In industrial and manufacturing applications, the ZV-NJ-2S is most often used as an overload protection switch. This type of switch is placed between the motor and the load (i.e., the device being controlled). When the motor begins to draw more current than it is rated for, the ZV-NJ-2S switch will sense the overload and trip the switch, shutting off power to the system until the source of the overload is addressed. This trip is usually instantaneous, meaning that it happens within a fraction of a second.

In addition to overload protection, the ZV-NJ-2S switch can be used in a variety of applications where a momentary short circuit needs to be detected. This could include applications where a circuit needs to be opened or closed as a result of another action, such as an electrical signal, or when a specified temperature or pressure is reached.

The ZV-NJ-2S switch is a reliable and cost-effective way to detect and respond to overloads, short circuits, and other conditions in industrial and manufacturing environments. Its simple design and robust construction make it ideal for use in a wide range of applications.
