Pushbutton switches, such as ALFD212620DNUA, are widely used devices for controlling electrical and electronic circuits. Pushbutton switches are used to initiate a circuit in a variety of application areas, including automotive, industrial, communications and consumer products. Pushbutton switches are available in many formats, from low profile DIP switches to high quality, momentary operated key switches.

Application Field of ALFD212620DNUA

The ALFD212620DNUA is a low profile, momentary, double pole, single throw switch, designed for applications requiring electrical isolation, very low current and high contact resistance. This type of switch is ideal for controlling small loads up to 2.5A at 125V, AC or DC. It can be used to switch on or off electrical circuits such as those found in consumer electronic devices, home automation, or industrial automation.

The ALFD212620DNUA is a versatile switch because it can be used in a variety of applications such as light switches, solenoid valves, motor starter circuits and alarm systems. Its small size and light weight make it well suited to applications where space and weight are key considerations, such as in light commercial and industrial applications. Its high contact resistance ensures reliable operation in more demanding applications.

Working Principle of ALFD212620DNUA

The ALFD212620DNUA is an electro-mechanical switch containing metal contacts that close or open when a user presses the switch. Inside the switch are two metal contacts that are electroplated with a thin layer of gold or silver. The switch is designed to be depressed with a light action and to make contact when released.

When the switch is pressed, the metal contacts are forced together, forming an electrical connection. This connection is broken when the switch is released and the contacts move away from each other. The switch is designed so that the contacts can operate up to 2.5A at 125V AC or DC.

The contact resistance of the ALFD212620DNUA is very low, ensuring reliable operation in more demanding applications. It is also very resistant to corrosion, vibration and shock. The switch is also designed to be able to handle higher power loads without problem, making it ideal for use in higher power applications. The switch is also UL and CSA approved for safety.

Conclusion

The ALFD212620DNUA is a versatile, low profile pushbutton switch. It is well suited for applications requiring electrical isolation, very low current, and high contact resistance. Its small size and light weight make it well suited for light commercial and industrial applications. It is also resistant to corrosion, vibration, and shock and is UL and CSA approved. With its reliable performance and wide operating range, the ALFD212620DNUA is an excellent choice for a variety of applications.
