Snap action, limit switches are quarter-turn devices with a jigsaw set of moving parts, typically a movable bridge contact, and a stationary spring-loaded contact, that when rotated to a prescribed angle, snap into position. Specifically, D4NL-4CFG-B4-NPT snap action limit switches are compact, double-ended units equipped with a large operating force, allowing it to be used for multiple applications.

The application field of the D4NL-4CFG-B4-NPT snap action limit switch is broad, ranging from industrial, commercial, and municipal automation systems, to recreational electronics and robotics. They are especially well-suited for high-resistance and low-power/voltage applications, such as in motor vehicles, factory automation and robotics, and security systems.

The working principle of the D4NL-4CFG-B4-NPT snap action limit switch is relatively simple. It functions by placing the movable bridge contacts on two opposite and opposing sides of the device\'s body. When the device is triggered, the movable bridge contacts that were previously in contact will be instantaneously flipped into \'open\' position, while the other set of contacts will move into a \'closed\' position. This makes the device act as a two-position switch, where one side opens and the other closes.

The toggle action of the D4NL-4CFG-B4-NPT snap action limit switch is accomplished through the use of a coil spring and a plunger located in the base of the device. As the plunger is depressed by an external operator, the coil spring compresses and forces the movable bridge contacts to flip from one position to another. The toggle is durable and reliable, and can operate in a wide range of temperatures and vibration levels.

The D4NL-4CFG-B4-NPT snap action limit switch is highly adaptable and customizable, allowing users to select the type of contacts, actuation force, and the operating temperature to suit their intended application. They are also shock and vibration rated, and can withstand heavy impacts and pressure due to the materials used in their construction. In addition, they are available in several design options and configurations, including bifurcated and IPM contact versions.

In conclusion, the D4NL-4CFG-B4-NPT snap action limit switch is a reliable, durable, and highly adaptable device, ideal for a wide range of applications. It offers a spring-loaded design and operates through an internal coil and plunger, allowing it to rapidly switch contact positions between open and closed. The device is shock and vibration rated, highly customizable, and can be installed in a variety of configurations.
