Snap action, limit switches are electromechanical switches with an actuator and a contact mechanism, that are capable of providing feedback to operating and controlling circuits. Snap action, limit switches are versatile, reliable and widely used in a variety of applications. The product offered, the D4F-102-5D, is no exception; as it is suitable to be used in a range of applications and offers a wide range of features.

This product offers a no-check construct, and is considered to be of a miniature size, as the width is only 6mm and the thickness of the body is only 4mm. Not only is the size favorable for fitting into small spaces, but it also allows for an easier set-up, as it offers various snap positions for the snap-action lever. Moreover, as the base, actuator, and contact arm all come pre-assembled, there is no need for additional fixing steps. This product also offers a responsive action and quiet operation, while also providing protection against dust and water, and a high heat resistance.

The working principle of the D4F-102-5D is based on its snap-action mechanism, which allows for a quicker response and more reliable behavior. When the lever is pushed, a cam mounted on the lever does a 180 degree rotation and, in the process, activates the switch. This process is repeated for each operation of the switch. In addition, the contact arm is pre-assembled and therefore needs no configuration.

One main applications of the D4F-102-5D is elevators. The switch is directly fitted onto either the elevator door or the lift car, and allows for feedback to the controlling circuit when doors are opened and closed. In addition, it allows for various operations such as elevator car monitoring, hoistway/cabinet fan monitoring, and so on.

The product is also commonly used on automotive applications. Its quick response and design allows for a more reliable control of signals such as oil pressure, engine temperature, and road speed. This safety feature can be used in engine control systems, airbags, anti-lock brake systems, and so on.

Aside from automotive and elevator applications, the D4F-102-5D can also be found in a range of home appliances such as food processors, refrigerators, cookers and other kitchen appliances. Its small size and dust and water resistant capabilities makes it ideal in such applications, as it can easily fit and provide reliable performance.

In conclusion, the D4F-102-5D is a snap action, limit switch with a versatile design and a range of features. It can be used in a variety of applications and is suitable for home appliances, automotive, and elevator operations. It offers a quick response and reliable performance, making it a perfect device for various operational needs.
