Tactile Switch
B3F
Miniature, Space-Saving Tactile Switch
Provides Long Service Life and Easy
Mounting
• Extended mechanical/electrical service life: 10 x 10
for 12 x 12 mm type and 1 x 10
6
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, vertical type and high force types are available
as series versions
• Flux-tight base structure allows automatic soldering of the tactile
switches onto a PC board
• Gold plated models available for increased contact reliability, resistance to corrosive gas and insulation fault prevention for ion
migration in harsh environments
• RoHS Compliant
