Pushbutton Switches

A pushbutton switch is a switch which is activated by pressing a mechanical button. Pushbutton switches are available in a variety of designs and colors, and allow for a momentary or maintained switching operation. Pushbutton switches are commonly used to actuate an electrical circuit, providing either momentary or maintained control.

The AV1921000Q04 pushbutton switch is a miniaturized, momentary contact switch which is used for selecting a switch mode or for providing an external switch conduction path. It is an ideal choice for applications involving low voltage and current requirements. This pushbutton switch features an epoxy sealed housing that is RoHS compliant, a green LED indicator, a robust actuator design, and is rated to 3A at 125V AC.

Application Field

The AV1921000Q04 is used in a variety of applications, including control panels for automotive, safety, domestic appliance, and industrial machinery; as a momentary switch for audio or video equipment; and as a selection switch for medical equipment, computer peripherals, and other electronic devices.

Working Principle

The AV1921000Q04 works by closing an internal electrical contact when the button is pressed. When the button is released, the contact opens and the circuit is broken. The switch is considered “momentary” because it is usually operated only for an instant or a brief period. The switch is also considered “latching” because it stays in the same position until manually reset.

The AV1921000Q04 is also equipped with a built-in LED indicator which lights up when the button is pressed. This feature allows for easy visual indication of activation, making it ideal for a variety of applications.

Conclusion

The AV1921000Q04 is a miniaturized, momentary contact pushbutton switch that is ideal for a wide variety of applications. It features a robust actuator design, a green LED indicator, and a sealed housing. The switch is rated for 3A at 125V AC, and works by closing an internal electrical contact when the button is pressed.
