B3SL

Middle-stroke Tactile Switch (SMT)

Surface-mounting Sealed Tactile Switch.

Middle Stroke and Crisp Clicking Action.

• Sealed construction conforming to IP67 (IEC

60529) provides high contact reliability in dusty

environments. (* Excluding the terminal section.)

• Crisp click feeling and middle stroke with rubber

plunger.

• Embossed taping package for automatic mount-

ing.
