There are two types of switch tips for Telecasters. Import and USA switches come in two different dimensions. If you purchase a USA switch tip for an import switch, you'll be left with a loose tip. If you purchase an import switch tip for a USA switch, it won't fit.   

The USA slot is suitable for Fender, Oak Grigsby and CRL switches. The import slot is suitable for Squier and other Asian made switches.  

Import slot - 4mm x 1mm
