B3F Tactile Switch

A Wide Range of Models:
6 × 6 mm, 12 × 12 mm, Side-operated,
High-force, and Gold-plated.

  • Extended mechanical/electrical durability:
    10 x 106 operations for 12 x 12 mm type and 1 x 106 operations for the 6 x 6 mm type
  • Taped radial type, vertical type and high force types are available.
  • Gold plated models available for increased contact reliability, resistance to corrosive gas and insulation failure prevention for ion migration in harsh environments
  • Type B32 Key Tops are available for projected plunger models.
This web page provides an excerpt from a datasheet.
