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.
