The EVPAA202K is a tactile switch manufactured by Panasonic. Tactile switches are electromechanical devices used to close an electrical circuit when pressure is applied by a user. They provide tactile feedback to the user upon activation, confirming the switch operation.

Applications:

• Input devices for consumer electronics (e.g., remote controls, gaming consoles)
• Control panels for industrial equipment
• Button interfaces for automotive systems
• Medical devices requiring user input
• Instrumentation and testing equipment

Features:

• Compact size for space-constrained applications
• Tactile feedback for user confirmation
• High reliability and long lifespan
• Surface mount design for automated assembly
• Available in various actuation forces

Benefits:

• Easy integration into electronic circuits
• Clear user feedback, improving the user experience
• Durable and reliable operation in demanding environments
• Cost-effective solution for user input
• Reduces assembly time and costs

Additional Details:

The EVPAA202K has specific actuation force, travel distance, and electrical characteristics, which can be found in the product datasheet. The switch's contact resistance, insulation resistance, and voltage rating are also critical parameters. It is important to select a switch with appropriate ratings to match the application's voltage and current requirements. The operating temperature range is specified and should be considered for applications in extreme environments. This switch is often used in high-volume applications where reliability and consistent performance are crucial. The part should be reflow soldered according to the manufacturer's recommendations.
