Pushbutton Switches

Pushbutton switches are one of the most common types of switch found in computers and other electronic devices. They are usually small, rectangular buttons that can be pressed down to trigger an action. This action can be anything from turning on a light to starting a program on a computer.

The ALFD21120DNUS is a pushbutton switch designed for use in industrial settings. It features a double-pole configuration that allows for both momentary and latching operation. This type of pushbutton switch is often used for emergency stop applications, where it is important that the switch does not stay in the depressed position for long.

The ALFD21120DNUS has a maximum current rating of 3A, making it suitable for most applications. It is also RoHS compliant, meaning it is environmentally safe. The switch features a high level of contact reliability, making it a reliable and safe switch.

The working principle of a pushbutton switch is fairly simple. When the button is pressed, current passes through the contact plates, which then triggers an action. In order for the action to take place, the contact plates must remain touching one another. The electricity creates a connection between the two plates, creating an electrical current. When the button is released, the contact plates are broken, ending the flow of current.

The ALFD21120DNUS is capable of providing reliable and safe operation in industrial, commercial, and residential applications. It is often used in environments that require emergency stop operations, as its double-pole configuration ensures that the switch will not stay in the down position. Furthermore, its RoHS compliant rating means that it is environmentally safe.

Pushbutton switches, such as the ALFD21120DNUS, are a reliable and durable form of switch that are commonly found in most electronic devices. With a wide range of applications, these switches offer a great deal of flexibility in terms of operation and safety.
