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, 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
