Pushbutton Switches: AV2521M524Q04 Application Field and Working Principle

Pushbutton switches are components that are common in electrical circuits, and the AV2521M524Q04 is a specific part from the series. Pushbutton switches, also known as simply pushbuttons, provide a discreet and convenient way to toggle circuits in and out, without the need for any tools. This article explains the application field and working principle of the AV2521M524Q04.

Application Field

The AV2521M524Q04 is typically used in a range of control and automation products, typically in industrial and commercial settings. For example, the AV2521M524Q04 may be used in automatic machines in order to start and stop the machine\'s operations. It may also be used as an "abort" emergency style switch, in order to kill power to a circuit if an emergency occurs.The AV2521M524Q04 may also be used as a reset or enable control in control systems, offering fast and reliable control mechanics for power supply and circuit operation. This switch can also be used in momentary operation for a range of machine tasks and maintenance switches.

Working Principle

The AV2521M524Q04 works through a mechanical pressure contact system, relying on a plunger-style system with a button to actuate the two sets of contacts. This plunger system has been designed to reduce contact bounce, which is when the contacts rapidly contact and disconnect multiple times when the switch is actuated. This ensures reliable and consistent operation.The two contacts in the AV2521M524Q04 utilise a "make-before-break" contact, which means that both contacts are always making contact with each other until the switch is released, before breaking the connection. This is crucial for preventing damage and arcing between the contact points when the switch is actuated.The AV2521M524Q04 also features contact reinforcement, which reduces the wear and tear on the contact points and increases switch life expectancy. This is ideal for electrical applications that require multiple switch actuations, allowing the mechanical contacts to remain intact for longer periods of time.

Conclusion

The AV2521M524Q04 is a highly efficient and robust pushbutton switch from the series. It is used in a range of industrial and commercial applications, where consistent and reliable operation is required. The AV2521M524Q04 works through a mechanical pressure contact system and is designed to reduce contact bounce and wear and tear of contacts. With increased contact reinforcement, the AV2521M524Q04 is an ideal choice for applications requiring multiple switch actuations.
