This pack of two official Fender Pure Vintage Telecaster Top Hat Style Switch Tip/Knobs are in the classic design introduced originally on 1955 Telecaster guitars. The switch tips will fit imperial sized lever switches (e.g. CRL and Oak Grigsby) used on most Fender USA and made in Mexico guitars, they will not fit metric sized 'import' switches (most switches made in Japan or other parts of Asia).
