D4SL-N3GFA-D

Snap action, limit switches are used in various applications that require fast and accurate operation when activating and deactivating an electrical circuit. One of the most common switch types is the D4SL-N3GFA-D. This type of switch is an enclosed metallic housing or casing containing internal components that allow the switch to mechanically respond to an external force or stimulus.

Application Field

D4SL-N3GFA-D switches are usually used in electrical panel applications that require quick action, such as the opening and closing of contact points. The limit switches may also be used for door interlocks, industrial equipment, and fail-safe applications where an imminent danger may be present. Additionally, this switch is also used in commercial and industrial applications due to its construction using heavy-duty components.

Principle of Operation

When a force, such as a mechanical switch or an electrical impulse, is applied to the switch, the internal components within the metallic housing will cause a physical movement of the contact points, either opening or closing the electrical circuit. The switch is held in place by a spring that will allow it to move freely within the enclosure. When the external force is removed, the spring will return the switch to its original position.

The switch is also capable of providing a precise, adjustable range of activation and deactivation points. This allows the user to adjust the amount of pressure required to switch the circuit on or off, depending on the application. Additionally, the switch can also be adjusted for contact rebound, which allows for greater accuracy and reliability when used in applications with high switching rates.

The D4SL-N3GFA-D snap switch is a reliable and dependable way to ensure that an electrical circuit is activated and deactivated in a timely manner. With its adjustable activation and deactivation points, this limit switch is commonly used in industrial and commercial applications.
