B3F Tactile Switch
Through-hole-mounting Switches
in a Wide Range of Models:
6 × 6 mm, 12 ×12 mm, Side-operated
Models, Gold-plated Contacts, and
Radial Tape
• 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
• B32-series Key Tops mount to models with
projected plungers.
