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.
