U821SD8AV2GE Pushbutton Switches: Application Field and Working Principle

Pushbutton switches are a common type of electrical switch typically used to control the operation of a machine or device. Their use has become ubiquitous in modern life and they can be found in virtually every type of electronic device. U821SD8AV2GE pushbutton switches are specially designed to suit typical industrial and office applications, offering a high degree of safety and reliability. In this article, we will explore the application field and working principle of U821SD8AV2GE pushbutton switches.

Application Field

U821SD8AV2GE pushbutton switches are most commonly used for controlling machine equipment, such as automatic doors, motorized gates, and power hot plates. They are also used in industrial machinery to control complex machinery processes, such as switching on and off a drill or lathe. These pushbutton switches are particularly well suited to controlling process automation due to their low cost and reliable performance. Additionally, they can be used to control the operation of pumps, fan motors, and conveyors in industrial and office settings.

Working Principle

U821SD8AV2GE pushbutton switches use mechanical contacts to control the direction and intensity of electric current. They consist of two electrical contacts, the pusher and the accompanying spring. When the user pushes down the pusher, the spring pushes the contacts against each other, thus creating a circuit that is then used to power the machine or device. A wide range of pushbuttons offer various types of contact, such as momentary, latching, fused, and non-fused contact. In addition, some types of U821SD8AV2GE pushbuttons are equipped with multiple poles and multiple pairs of contacts.

Position to Position Switches

U821SD8AV2GE pushbutton switches are also commonly used as position-to-position switches. With a position-to-position switch, the user can switch the electrical contact from one position to another. As such, these switches are often used to control the operation of multiple devices with a single switch. For example, they can be used to control the operation of a conveyor belt, a door, and a light switch all with a single switch and without using multiple switches.

Additional Features

U821SD8AV2GE pushbutton switches also have several additional features that make them particularly well suited for controlling machinery and certain types of processes. For instance, many models are equipped with a built-in illumination feature that allows for visual indication. They also come with optional integral lockout features, which allow only authorized personnel to access and control the equipment.

Conclusion

U821SD8AV2GE pushbutton switches are a versatile and reliable type of electrical switch that can be used to control the operation of machines or devices in both industrial and office settings. They are particularly well suited to controlling complex machinery processes, as well as position-to-position switching operations. Additionally, they come with additional features, such as illumination and lockdown, that add an extra layer of safety and reliability.
