Snap action limit switches, such as D4N-2172, are electromechanical devices used to detect the physical position of an object, for example, a lever or a roller. They are designed to activate, or open and close, as a result of pressure, tension, or physical displacement of a lever, a roller, or some other mechanical element. When a limit switch is opened (a break in the contact, or a remote signaling device), it then causes a different circuit to be switched on or off, which in turn activates a given process or sequence of events.

The principle of snap action limit switches lies in their design. As the lever or roller is moved, the condensed mechanical energy is released and absorbed by the switch as movement of its internal components, and then the switch is able to provide contact closure or opening. The switches are designed to produce an instant contact closure or opening and provide stability for either of these conditions.

The D4N-2172 snap action limit switch is an economical and small size type with the combination of a molded terminal box and a large wiring hole. It has actuators that react to pressure and tension given by a lever or roller, and is constructed with a combination of high quality plastic and copper alloy parts. It offers a maximum rating of 12A 120V AC for electrical switching and opens as a result of a limit, roller, or lever.

The D4N-2172 switch is ideal for applications in which a small, cost effective switch is required. It is particularly suitable for applications that require the switch to activate a process or sequence of events, or when the switch needs to be able to open and close as a result of pressure, tension, or physical displacement of a lever, roller, or some other mechanical element.

The switch is typically used in machinery and other industries to detect the position of objects, including levers and rollers, and to ensure that the process or sequence of events is completed quickly and accurately. It can also be used in audio and visual applications to switch on or off a signal or series of signals. The D4N-2172 switch is also used in safety systems to detect the presence of a person or object, and to ensure that the safety systems are activated as required.

The D4N-2172 snap action limit switch is a reliable, cost effective, and small size type switch which is suitable for many different applications in the industrial and audio-visual markets. It is designed to activate, or open and close, as a result of pressure, tension, or physical displacement of a lever, a roller, or some other mechanical element and provides immediate contact closure or opening.
