B3F Tactile Switch
A Wide Range of Models:
6 × 6 mm, 12 × 12 mm, Vertical, and High-force.
  • A positive click action plus a long life equal to that of a no-contact switch.
  • Radial models (taping specifications) that allow the use of general-purpose radial taping parts insertion machines have been added to the series.
