B3S Sealed Tactile Switch (SMT)
Surface-mounting Tactile Switch for
High Contact Reliability
• Sealed construction conforming to IP67 (IEC-
60529) provides high contact reliability in loca
-
tions exposed to dust or water. (* Excluding the
terminal section.)
• Surface-mounting terminals for high-density
mounting.
• Ground terminal available to protect against static
electricity.
• Available in embossed taping packages for auto-
matic mounting.
■ List of Models
6 × 6 mm B3S-1000
Note: Switches in bags must be ordered in units of 100 Switches, and Switches on embossed taping must be ordered in units of 1,000
Switches.
