These days the 5 way Strat switch is taken for granted but in the first 3 decades of the Stratocaster’s history (during the 1950’s, 60’s and most of the 70’s) the standard switch fitted at the Fender factory was a 3 position selector. The classic in-between pickup sounds were still achievable but players had to resort to carefully balancing the lever between positions to get the combination of bridge and middle and middle and neck pickups, now commonly referred to as positions 2 and 4 on a 5 way switch. It was only around 1977 did Fender start to fit a 5 way switch as standard to make it much easier to select all 5 tones.

Naturally, this 3 way switch is perfect for the 2 pickups on a Telecaster, allowing for bridge, bridge and neck and neck-only pickup selections.
