 浏览型号SDTM-648-YTR的Datasheet PDF文件第2页 
The SDTM Series is currently available,  
although not recommended for new  
designs.  
Features  
■ Available sharp click feel with a positive  
tactile feedback  
■ Ultra-miniature and lightweight structure  
suitable for high density mounting  
■ Insert molding in the contact with special  
treatment prevents flux buildup during  
soldering and permits autodipping  
■ Very economical with high reliability  
■ RoHS compliant*
