Tactile Switch B3F
Miniature, Space-Saving Tactile Switch Provides
Long Service Life and Easy Mounting
■ Extended mechanical/electrical service life:
10 x 106 operations for 12 x 12 mm type and
1 x 106 operations for the 6 x 6 mm type
■ Ideal for applications such as audio, office
and communications equipment, measuring
instruments, TVs, VCRs, etc.
■ Taped radial type, ver tical type, high force type,
and gold-plated contact type are available as
series versions
■ Flux-tight base structure allows automatic
soldering of the tactile switches onto a PC board

Hints on Correct Use
■ TAPED RADIAL (AUTO INSERTION) PACKAGING
• Tactile switches packed on tape are placed into packing
boxes as shown below.
• Number of switches per box: 1,000
• Tape may be drawn from the box either from the top or from
the bottom.
■ TAPING STRENGTH
The tactile switches will not release from the tape when pulled in
directions A and B at the following forces.
A: 500 g
B: 100 g
