Pushbutton switches are a type of switch with a plunger, or "push button" on the outside of a device that allows a user to control circuitry within. AV1921D512R04 is a common type of pushbutton switch and is frequently used in a wide variety of applications, including industrial settings, consumer electronics, and more. This article will discuss the AV1921D512R04’s application field and working principle.

Applications

The AV1921D512R04 pushbutton switch is a compact, low profile switch with a 6A momentary contact rating. It is designed to fit in tight spaces and is perfect for applications requiring multiple mounting directions. Additionally, the switch offers superior resistance to environmental conditions due to a special epoxy sealing mold. As a result, this type of switch can be used in a variety of settings, including but not limited to: automotive, marine, industrial control, instrumentation, and medical equipment.

Moreover, the AV1921D512R04 pushbutton switch is designed to fit a variety of mounting holes, making it a flexible option. It is also suited for use with large actuators, as the switch has a large diameter actuation button and is able to withstand high table pressure. Additionally, the switch has a low current rating, making it suitable for battery-powered and other energy-constrained applications.

Working Principle

At the heart of the AV1921D512R04 pushbutton switch is a set of electrical contacts, with one side being normally open, or “off” and the other side being normally closed, or “on”. When the plunger is pressed, the contacts move together, allowing current to flow. This action completes an electrical circuit and can cause a variety of functions to occur, depending on how the switch is wired into the circuit.

The AV1921D512R04 pushbutton switch has a special feature that sets it apart from many other types of pushbutton switches. This switch has an LED indicator that can be lit when the plunger is pressed. This indicator is helpful in industrial applications where it is necessary to take an action only when the button is pressed. The LED indicator can also indicate failure of the button or be used to indicate the current status of the switch.

The AV1921D512R04 pushbutton switch is reliable and highly customizable, making it the perfect choice for a wide variety of applications. Whether it is being used in automotive, industrial, or instrumentation settings, this switch is easy to install and maintain, and can provide reliable and consistent operation over many years.
