The AV02820KMZQKUL is a pushbutton switch, which is a type of control switch used to manually engage and disengage electrical circuits. Pushbutton switches are most commonly known for their use as doorbells, and can be found on a variety of devices from computers to home appliances.

Application Field

Pushbutton switches have a variety of uses due to their simple design and low cost. They are commonly used in domestic and commercial appliances, security systems, telephone systems, medical equipment, vending machines, and many other applications. Common uses include controlling circuits that power objects such as lights, motors, and security systems.

Pushbutton switches are also used as input devices on computers, where they can be used as triggers for special functions. For example, on a laptop, a pushbutton switch can be used to activate the touchpad, access special menus, or control other external hardware.

In addition, pushbutton switches are often used in industrial applications such as machine control and process automation. They can be found in production lines, in process control systems, and in other applications where precise control is required.

Working Principle

Pushbutton switches work by closing and opening an electrical circuit. When the switch is actuated (pushed or clicked), a plunger interrupts an electrical circuit causing a change in the current or voltage. When the plunger is released, the switch returns to its original state, re-establishing the electrical connection.

Modern pushbutton switches feature a variety of features such as LED indicators to show the current state of the switch, and auxiliary contacts to provide additional control. Pushbutton switches are available in many different designs and can be used in both simple and complex applications.
