D4SL-N3NFA-DN

Snap Action

Snap action switches are contact elements that are used to control electric current. Snap action switches can provide both single and double pole switching, as well as single and double throw switching. They are typically used in applications where reliability and long life are required.

The D4SL-N3NFA-DN is a snap action switch designed for harsh environment and high-vibration applications. The switch is designed with a Tamper-Proof housing and also features a metal actuator that provides positive latching action when depressed. Additionally, the switch is rated for up to 10 million mechanical cycles, ensuring a long, reliable service life.

Working Principle

The D4SL-N3NFA-DN is designed with a snap action mechanism that operates in conjunction with an actuating arm. As the actuating arm moves towards the switch contacts, electrical contacts are closed and a latch is activated. This latch keeps the contacts closed and allows the current to remain on until the actuating arm is released. Once the actuating arm is released, the contacts open and the current is cut off.

Application Field

The D4SL-N3NFA-DN is designed for use in harsh environments where vibration, shock, and temperatures are high. It is most commonly used in military and aerospace applications, as well as in industrial process control equipment. It is also used in medical devices and equipment, as well as in automotive and off-road applications.

The switch is designed to provide reliable switching performance even in the most demanding applications. Its superior design and robust construction make it an ideal choice for high-reliability applications.
