Snap Action, Limit Switches

D4NL-2GFG-B4 snap action limit switches are used in a wide variety of applications, including automotive, circuit protection, energy management, and industrial control. These types of limit switches are designed to provide precise electrical contact at a predetermined point in an electrical power system. They are often used to disconnect the power in an emergency situation, to control the switching of high voltage or to act as a safety interlock for high-precision system functions. Snap action limit switches are also commonly used to detect when a limit has been reached in a mechanical system.

D4NL-2GFG-B4 snap action limit switches use a mechanical spring-and-pin mechanism to actuate the contacts. When touched or pushed, the pin will compress the spring and move in a linear motion. The motion of the pin will cause the contact arm to move, breaking the contact and disconnecting power. The contact arm can then return to its original position, once again making contact when the pin is released. This movement creates an electrical signal that can be used to activate, control, or deactivate functions in an electrical system.

D4NL-2GFG-B4 snap action limit switches are designed with a hardened metal contact arm, which gives them a high degree of durability and reliability. Most units are equipped with an adjustable reset mechanism, which prevents damage if the switch is actuated too quickly. This feature also allows for precise electrical contact points, providing greater control for the user. The contact arms are sealed in a die-cast zinc alloy or stainless steel housing, which helps protect them from dust, debris and moisture. Most units are rated for up to 10A and 250 Vac and come with a UL-listed seal of approval.

In addition to industrial and automotive applications, D4NL-2GFG-B4 snap action limit switches can also be used in consumer products. They are often used in refrigerators and freezers to detect the temperature within the appliance. They can also be used in security systems, to detect when a door has been opened or closed. In some cases, they may be used to control the position of robotic arms, giving precise control over their actions.

Overall, D4NL-2GFG-B4 snap action limit switches are a reliable and precise way to control the flow of electricity. They have a wide range of possible applications, making them a great choice for a variety of electronic systems. They are durable and reliable, and they come with a UL-listed seal of approval, giving users confidence in the quality of the products they purchase.
