Rocker Switches

Rocker switches are electrical switches that are used in many applications. They are typically oval in shape, and feature a flat base with a paddle that rocks back and forth to open and close. This type of switch is popular because it is easy to use and can be large enough so that users with wide fingers can find their way around.

The D201J12S205QA rocker switch is particularly versatile, widely used in many industrial and consumer applications. The toggle switch is designed to fit into a standard panel cutout, and its two terminals allow for two operating positions. The rocker switch can be used for on/off control or for changing between two functions, such as high and low settings.

Working principle

The D201J12S205QA is a single-pole, double-throw (SPDT) switch. This means that the switch has two terminals that can be connected to two circuits, allowing for on/off control or changing between two functions. When the paddle is in the down position, the contacts will be made to the first pair of terminals. When the paddle is in the up position, the contacts will be made to the second pair of terminals.

The switch is designed with a knob that rocks back and forth. As the knob is pushed in one direction, the contacts are made to one pair of terminals while the opposite contacts are disconnected. Conversely, when the knob is pushed in the other direction, the contacts are made to the second pair of terminals, while the first pair of contacts are disconnected.

Application field

Rocker switches are used in a wide range of applications, from consumer electronics to industrial machinery. The D201J12S205QA is often used in medical, consumer and industrial applications. In medical spaces, it is used to control lighting in areas where a light switch may not be readily available. In consumer electronics, it is commonly incorporated into gaming consoles, computer keyboards, and more. In industrial settings, it is commonly used in machines to control motors, conveyor belts, and other equipment.

The rocker switch can also be used in vehicles, such as cars, boats, and airplanes. It is often found in dashboards to control radio settings, lights, ventilation, and other functions. It is also frequently integrated into audio systems, control panels, and navigation systems.
