Pushbutton Switches

Pushbutton switches, or push button switches, are ubiquitous in everyday life. Push buttons are used to power up machines, activate control functions and even operate the doors in buildings. In many cases, the narrow-profile switches are designed to fit into even the tiniest spaces, providing reliable performance in even the most challenging environments.

A particular type of pushbutton switch is known as an A3PA-90A11-24AA pushbutton switch. This aviation-grade, momentary pushbutton switch is a heavy duty, diecast aluminum switch with a diameter of 1/2" and a travel of 2.2mm. The terminal blocks of the switch are gold plated, providing effective performance in environments with high levels of environmental stresses and corrosive agents.

When it comes to application fields, A3PA-90A11-24AA pushbutton switches are most commonly found in aviation, marine and military applications. The rugged construction, reliable performance and secure design make it well-suited for use in these types of applications. It is often used to control and activate electrical components, switches, relays, pushbuttons and even door access control systems.

The working principle of the A3PA-90A11-24AA switch is quite simple. The momentary action of the switch is activated when the button is pressed, providing a momentary on/off level voltage. This ensures that power is supplied only when the pushbutton is actively pressed, helping to reduce energy consumption and ensure secure operations.

The design of the switch is also highly secure, as the dust and water-resistant construction prevents any dust or moisture from coming into contact with the internal contacts. Additionally, the thick diecast aluminum material of the housing helps provide optimal protection for the internal components, ensuring reliable performance in even the most challenging environments.

In conclusion, the A3PA-90A11-24AA is an aviation-grade, momentary pushbutton switch ideal for use in industrial applications such as aviation, marine and military. With its rugged construction, reliable performance and secure design, the switch provides solid performance in even the harshest conditions. The dust and water-resistant design prevents any dust or moisture from compromised the switch’s internal contacts. Lastly, its momentary action is perfect for controlling and activating electrical components, switches, relays, pushbuttons and door access control systems.
