Electric Guitar Switches - a Beginner's Guide
Confused about what the switches on your guitar do? We're here to help

These are usually a three-position switch. When the switch is flipped up (towards you as you're holding the guitar), the pickup that is closest to the guitar's neck (the "neck pickup") is usually selected by itself. On some guitars, this setting is marked "Rhythm." When the switch is flipped down (away from you and towards the floor), the pickup that is closest to the bridge (the bridge pickup) is activated, and the neck pickup is turned off. This setting is marked as "Treble" on some guitars. A middle switch position lets you use both pickups simultaneously.
Most Squier and Fender guitars (and many others) use a blade style switch for pickup selection. These come in two common varieties - three-position and five-position switches. Externally the two look the same, and the only way to know what you're dealing with is to click through the settings and see how many there are. Three-position switches are more commonly found on two-pickup guitars, while the five-position blade switch is a common feature on guitars equipped with three pickups, like the Stratocaster shown in Figure 2.
Three-position blade switches are wired and function similarly to a three-position toggle switch, with one setting (usually with the switch slid fully "forward" or towards the neck) activating the neck pickup, a middle position where both pickups are active, and a third where only the bridge pickup is turned on.
Five-way blade switches can be wired in a variety of ways, but the most common has the bridge pickup turned on by itself when the switch is thrown all the way "down", a combination of the bridge and middle pickups in the second position, the middle pickup alone in the third (or middle) position, the middle and neck pickups together in the fourth position, and finally the neck pickup alone when the switch is flipped "up" (or towards the neck) all the way.
Rotary switches (Fig. 3) often look like ordinary knobs, and they rotate like a volume knob does, but they actually click between different switch positions when the knob is turned. Rotary switches are sometimes used for pickup selection (such as on the vintage Fender Electric XII and some Paul Reed Smith models), but they're also commonly used as tone controls too, such as with the Gibson Varitone control.
Even less common than guitars equipped with rotary switches are guitars with individual pushbutton on/off switches, or individual on/off mini toggle or slide switches (Figure 4) for activating each pickup. These require multiple switch movements to turn one pickup off and turn another one on, which takes extra time and effort, but they do have the advantage of providing more pickup combinations on guitars with three pickups than what you'll be able to achieve with a five-position blade switch on its own.

When is a pickup switch not a pickup switch?
There are some single-pickup guitars, such as the Fender Esquire, that have what look like pickup select switches on them, which seems kind of unnecessary, since there's only one pickup on that guitar. What gives? Well, in the case of the Esquire, the three-position switch is wired to provide different tonal options, just as a regular pickup selection switch does, but it achieves them in a different way. Instead of switching between different pickups, one position gives you the sound of the pickup alone, with the tone control completely bypassed, the middle position gives you the sound of the pickup but adds in the usual tone control, while the third position adds a capacitor that dramatically rolls off the treble, giving it a very deep, bass-heavy sound. Other guitars with single pickups are out there with similar switch arrangements that may be wired to different tone caps, or pickup coil splits or other similar tone altering functions.
Other switches for other tasks
In addition to the main pickup selection switch, some guitars have additional switches that provide extra functions. Oftentimes these take the form of additional smaller-sized toggle switches that are mounted on the guitar's body or pickguard. In fact, some guitars have a bewildering assortment of switches on them - enough that they can occasionally be a bit confusing and perplexing for even experienced guitarists!
Sometimes where these switches are located isn't immediately obvious because they're built into the guitar's other controls. The Volume and / or Tone rotary controls on some electric guitars have "push / pull" (Figure 5A and 5B) or occasionally "push / push" switches built into them that activate various features, such as pickup coil tapping (which turns a two coil humbucking pickup into a single coil pickup by disabling one of the humbucker's two pickup coils), or by inverting the polarity / phase of one of the pickups, which creates a weaker, hollow, out-of-phase sound when that pickup is combined with another one.

Other times, mini toggle type switches are used for accessing features such as built-in preamps and boosts, but these are far less common.
Just how do you know for certain what all of the various switches on a particular guitar model do? You can always ask the store clerk, check the manual (if one was included with the guitar), or try the manufacturer's website - many companies list that information online, even for their discontinued models. Of course if you're really stumped, you can always try playing "stump the experts" and ask the knowledgable folks over on the Harmony Central Electric Guitar forum… -HC-
