Switches for Automotive Board Level Applications

Common Automotive Board-Level Applications

Board-level switches are used throughout modern vehicles to provide compact, reliable control and input functions. Depending on the vehicle system and control interface, tactile and snap-action switches can support user controls, electronic interfaces, sensing, and other PCB-mounted functions.

  • Driver & User Controls
    Compact tactile switches can provide reliable input for dashboard, console, and other vehicle control interfaces.
  • Infotainment & Multimedia
    Board-level switches can be used for compact controls within infotainment, audio, navigation, and other electronic interfaces.
  • Interior Lighting Controls
    Illuminated and tactile switch designs can support control interfaces for interior lighting and related vehicle functions.
  • Electronic Control Panels
    PCB-mounted switches provide compact input solutions for electronic control panels where space and consistent actuation are important.
  • HVAC & Climate Controls
    Tactile and multi-directional switches can support user inputs within vehicle climate-control interfaces.
  • Sensor & Control Interfaces
    Compact switches can interact with electronic control systems and provide input or position-related functions within automotive assemblies.
