Sealed Tactile Switch (SMT)

Surface-mounting Switches with a

Sealed Structure for High Reliability.

Available on Embossed Tape

• Sealed construction conforming to IP67 (IEC-60529)

provides high contact reliability in locations 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.
