B3W Tactile Switch (Sealed Type)
Allows Cleaning After Soldering with Alcohol Solvents
  • Internal sealed construction allows immersion cleaning with alcohol solvents after soldering.
  • Thin, compact construction in both 12 × 12 mm and 6 × 6 mm sizes.
  • Snap-action contact construction for a positive click action.
  • Available with ground terminals for protection against static electricity.
  • Sealed construction also provides high reliability in dusty environments.
