SW3831D/U

Rocker switches have been employed in a wide range of applications, including industrial, automotive, audio, telecom and numerous other industries. Among them, the SW3831D/U model is suitable for application in such areas. This article introduces the application field and working principle of SW3831D/U and elaborates its features.

SW3831D/U is a kind of switch typically with two positions, on, off and in cases three positions, on–off–on. It is available in a variety of configurations and two or one pole styles. It is rated up to 15 A at 120 VAC, so it is typically used to control a variety of electrical devices. For example, it is used to control the devices like warmers, refrigerators, audio equipment, lights and so on.

SW3831D/U is also typically used in commercial aircraft, trains, and motor vehicles where it is integrated into interior lighting, windows and fan controls. Furthermore, it is often used in navigation systems and electronic instrument panels, either for state input or display. It is also used in medical equipments and industrial production, such as motors, engines, fuel systems, or pumps.

The primary component of SW3831D/U is a contact assembly consisting of a rocker arm, resilient actuator and electrical contacts. The rocker arm, usually made of plastic, is the visible portion of the switch, mounted directly to a display panel, dashboard, or door. The resilient actuator has a base, usually made of metal such as stainless steel, and incorporates the electrical contacts. When the rocker arm is pressed in one direction, a plunger depresses one of the electrical contacts, and raises the other one, and when the rocker is pressed in the other direction, the plunger depresses the other contact.

The switch contacts remain in the on-off-on (or on-off) state depending on the application. Generally, pressing the rocker arm sets the contacts in one state, e.g. on, and pressing the arm again sets the contacts in the other state, i.e. off. This is how SW3831D/U works and the process repeats with each press.

The SW3831D/U is a superior unit that usually works perfectly as a rocker switch. It has the following properties:

Therefore, it is widely used in a variety of environments, such as medical devices, aircraft, automobiles, electronic instruments and industrial applications.

The SW3831D/U model is a superior unit from the omnipotent rocker switches. It is suitable for application in many industries, and its electrical contacts can be easily and reliably changed with each press. It is economical, small sized and cost-effective, while it is rated to 15 A at 120 VAC, making it one of the most reliable rocker switches.
