A8L-21-12N2 Datasheet/PDFA rocker switch is an electrical component that functions as a type of switch that can turn an electrical circuit on/off or control power to an electrical device. The A8L-21-12N2 rocker switch is one such component, with a range of uses and applications.
As its name implies, a rocker switch is a rectangular piece of plastic or metal, with a hollowed out center, that has two knobs or paddles on either side, typically spring-loaded. When a user presses a knob, it causes the switch to pivot, which activates the electrical circuit. A rocker switch allows easy control of several circuits using just one component, reducing complexity in many electrical designs.
The A8L-21-12N2 is a common, compact rocker switch commonly used for controlling a variety of appliances, from fans to lighting. This particular model features 2 poles, or contacts, and 12 terminals, allowing it to control up to three circuits at once. Its design also makes it very simple to install, making it a popular choice for many household and industrial applications.
The A8L-21-12N2 rocker switch can also be used to control AC or DC currents, depending on the application. It is designed with a double-throw, meaning that it can switch between two different circuits. This makes it ideal for a wide range of projects, from controlling appliances to powering window-mounted air conditioners.
A8L-21-12N2 rocker switches are also popular due to their durability. They are rated for up to 6A at 250V AC and 10A at 12V DC, meaning they are well-suited for both industrial and residential applications. This means they can be used to power larger appliances such as televisions and air conditioners without any issues.
The working principle of the A8L-21-12N2 switch is fairly simple. The paddles are spring-loaded, meaning that when pressed, they cause the switch to pivot, which activates the electrically conductive contacts inside the switch. When the switch is in the Off position, the contacts are open, and no current passes through. When the switch is pushed to the On position, the contacts close, and current passes through, completing the circuit.
In conclusion, the A8L-21-12N2 is a highly versatile and reliable rocker switch, with a range of uses and applications. Its double-throw design and 12 terminals make it easy to install and use in any number of electrical circuits, from residential light switches to industrial power control systems. Its sturdy design and construction mean that it will remain reliable for years to come.
