B3U

Ultra-small Tactile Switch (SMT)

Ultra-small Surface-mounting Tactile

Switches with High Contact Reliability

(1.2 × 3 × 2.5 mm (H × W × D)

• Smallest class in the industry for high-density

mounting of compact devices.

• Surface mounted: Ideal for high-density mounting.

• Models with ground terminals are available for

protection against static electricity.

• Available on embossed tape: Ideal for automatic

mounting.
