Sealed Tactile Switch
B3W
Through-hole-mounting Switches
That Are Mounting-compatible
with B3F Series.
Sealed Structure for High Reliability
• Sealed construction conforming to IP67 (IEC60529) provides high reliability in locations
exposed to dust or water. (* Excluding the terminal section.)
• Available in two sizes: 6 × 6 mm and 12 × 12 mm
sizes.
• Ground terminal available to protect against static
electricity.
• B32-series Key Tops mount to models with projected plungers.
RoHS Compliant
