Snap Action, Limit Switches have a wide variety of applications and are used in many industrial and domestic systems. One type of snap action switch is the D4NL-2AFA-B4, which has a built-in sensor that helps prevent over-travel and shock, while still providing a good level of response. The D4NL-2AFA-B4 is a type of limit switch with a built-in over-travel protection feature.

The D4NL-2AFA-B4 limit switch utilizes a two-phase lever action to actuate a contact element for use in a variety of applications. The main feature of this switch is its ability to switch at a predetermined point of closure, allowing it to act as a limit switch. When the actuator is closed, the contact element moves with it and the electrical connection is made. The over-travel protection feature prevents the contact element from passing the predetermined limit point and reduces the risk of electrical damage.

In terms of working principle, the D4NL-2AFA-B4 limit switch uses a plunger-style actuating mechanism. When pressure is applied to the plunger, the contact element is forced to move further, resulting in a contact closure. This action is reversible, meaning that the contact element can be released when pressure is relieved from the plunger.

The D4NL-2AFA-B4 limit switch is widely used in many different types of machines, appliances, and industrial systems. The over-travel protection feature provides an added layer of safety, reducing the risk of accidental contact closure and resulting electrical damage. In addition, the limit switch is also used in UL-listed products, providing an extra layer of protection.

The D4NL-2AFA-B4 limit switch is a reliable and effective way to restrict the contact element from travelling too far and protect against over-travel. With its built-in over-travel protection feature, this switch is a great choice for many industrial and domestic applications. It provides a reliable and consistent response when actuated, making it a popular choice for many applications.
