Snap Action Limit Switches are often used in industrial applications to detect the physical position of something and to accept mechanical force to open and close the electrical circuit when a predetermined value is attained. The D4N-8120 is a standard Snap Action Limit Switch designed to detect the position of moving objects in a wide variety of industrial applications.

The D4N-8120 is a high precision limit switch with a snap action mechanism that has both open and closed circuits. It is capable of accurately detecting and responding to the displacement of a movable object by quickly switching between the open and the closed circuit positions. This snap action operating characteristic of the switch ensures that any operation conditions within its specified range can be met with a constant, quick and accurate switching operation of the contacts.

The D4N-8120 is able to detect a wide range of displacement levels and also has an adjustable activation point for various application fields. With its built-in snap action mechanism, it is able to respond accurately even to fluctuating or unpredictable load forces. Its design includes a metal housing that provides superior protection against dust and moisture.

The D4N-8120 can be used in a wide range of applications including machines for the automotive, industrial, medical, and aerospace industries. It is designed to detect the position of moving objects such as a machine’s movable part, a conveyor’s shaft, a door, or a lever. It is also commonly used in appliances, toys, agricultural equipment, and construction machinery.

The working principle of the D4N-8120 is relatively simple. The switch is composed of a movable contact which is connected to an actuating rod. When an external force is applied to the rod, it causes the movable contact to move in accordance with the displacement. This then causes the contact to move up or down a switch parallel rail, allowing the circuit to be opened or closed.

The D4N-8120 has a highly sensitive and accurate response and is extremely durable and reliable. Thanks to its robust construction and reliable design, this switch is able to ensure continuous operation in many different applications and hostile environments.
