Pushbutton Switches: A22L-DA-12A-11M Application Field and Working Principle

Pushbutton switches are important components for a variety of industrial and commercial applications. As technology advances, more types of pushbutton switches become available, such as the A22L-DA-12A-11M model. This article will discuss the application field and working principle of this specific model.

The A22L-DA-12A-11M model is a three-pole pushbutton switch designed for controlling a single circuit or two groups of circuits. It has an adjustable actuator with two- and three-position switching options. The switch is rated at AC 20A 250V or AC 10A 400V, making it suitable for residential and commercial applications. The switch is designed to be mounted on a flat surface, such as a door or panel, with a minimum allowable installation depth of 10mm.

The working principle of the A22L-DA-12A-11M model is similar to that of other pushbutton switches. The contacts are held closed when the actuator is pressed, completing the circuit. The contacts are held open when the actuator is released, thus interrupting the circuit. It is important to note that the contacts can only be opened when the actuator is in the OFF position. This prevents unintentional operation.

The A22L-DA-12A-11M model is ideal for applications such as lighting control, doorbell and alarm systems, and industrial control. It is strong and reliable, with a mechanical life of more than 1 million operations and an electrically life of more than 50 thousand operations. The switch is also resistant to temperature and humidity, making it suitable for installation in a range of environments.

The A22L-DA-12A-11M model is suitable for a variety of applications, but its working principle remains the same. The contacts are held closed when the actuator is pressed, completing the circuit. The contacts open when the actuator is released, thus interrupting the circuit. Its strong construction, resistance to temperature and humidity, and long service life makes it one of the most popular pushbutton switches available.
