D4N-8220 snap action, limit switches are designed for industrial automation applications. They are designed for the detection of a predetermined position, and when activated, the contact remains open or closed until reset. This type of switch is used in a variety of applications, such as detecting the position of parts in an assembly line, monitoring door and window positions, and detecting the presence of objects on a production line. They are also used in robotics and industrial automation systems, control systems, and safety switches.

The D4N-8220 snap action and limit switches are constructed with a metal housing, secured with two screws to ensure reliability. They are available in various sizes and styles for specialized applications. The housing is designed to withstand common environmental influences, such as temperature and moisture. The switch contact is made from stainless steel, which is corrosion resistant. The contact can be easily replaced in the event of wear or damage.

When activated, the switch contact can remain open or closed. This is determined by the configuration of the switch actuator. There are two different types of actuators, a plunger and a roller. The plunger type has a spring-loaded button that is pushed in to activate the switch contact, while the roller type has a cylindrical roller that rotates to make contact. The switch also has selectable modes, including momentary and alternate action, which will determine the behavior of the contact when it is activated.

The working principle of the D4N-8220 snap action and limit switches is based on the force of contact between the switch contact and the actuator. When the actuator is moved in the correct direction, it pushes the contact against a spring-loaded arm and activates the switch. The spring pressure keeps the contact in the activated position until it is released. The switch contact can be configured to open or remain closed, depending on the configuration.

The D4N-8220 snap action and limit switches are designed for reliable operation and are used in many industrial automation applications. They are easy to install and maintain, and the contact can be easily replaced if needed. They are an ideal choice for applications that need an accurate and reliable switch with a minimum amount of maintenance.
