The D4N-9222 -- a snap action, limit switch -- is a type of electrical switch, used to control the movement of objects, machines, and other applications. It works by sensing physical presence or pressure and is typically used in areas where safety is an issue.

This switch activates quickly and with a single action. It features a variety of features, such as differential trips, adjustable travel, adjustable pre-travel and adjustable reset. It is also available in different pole arrangements and has an adjustable contact pressure.

D4N-9222 is used for a wide range of applications. It can be used for partial stroke testing, limit switching, door interlocks, chain pull applications, air-break switch applications, instrument safety check, and a wide range of other industrial applications.

Working Principle

The D4N-9222 snap action, limit switches work through a mechanism that is similar to other types of switches. It consists of a stationary contact relay and a moving contact relay. To activate the switch, the contact needs to move in order to make the electrical connection.

When the contact movement is triggered, the force of the load is transferred to the contact snap, causing it to move. This causes the contact to make contact with the stationary relay, which in turn triggers the electrical connection.

The D4N-9222 limit switch is designed to be able to handle various pressures. It can be configured to disconnect at various levels of pressure, and is suitable for use in areas where safety concerns are paramount.

The D4N-9222 snap action, limit switch also includes a number of other features, such as built-in shock absorbing properties, to prevent false triggers, status monitoring capabilities and superior electrical isolation characteristics.

The switch can be tested to ensure it is functioning correctly and to check if it is appropriately calibrated. This allows it to work efficiently, accurately and consistently in demanding applications.
