Features
■ Through-hole and SMD styles available
■ Available sharp click feel with a positive
tactile feedback
■ Ultra-miniature and lightweight structure
suitable for high density mounting
■ Designed for washing after soldering
■ RoHS compliant*
The ST(H,M,J,R)W Series is currently
available, although not recommended
for new designs.
■ Insert molding in the contact with special
treatment prevents flux buildup during
soldering and permits autodipping
