Mini
toggle switches
The most common mini toggle switches used in guitar
wiring are DPDT (double-pole, double throw). Although
all of our mini toggles are DPDT, two of them have
three positions. Confused? Well, "throws"
don't necessarily correspond to positions, so refer
to diagram #11 for what is happening for
each position.
A mini toggle switch has a wide variety of functions
in guitar wiring. The mini toggle is not designed
for any specific reason—you have to tell it
what to do. Some typical uses for mini toggle switches
include switching phase; series/parallel wiring;
coil-cutting; pickup selector, series/split/parallel
switch; on/off switching; and more.
Push-Pull Pots
This is yet another powerful tool to the guitar
builder or repairman. Two electrically independent
components are controlled by a single knob shaft.
When the shaft is rotated, the potentiometer (and
whatever it's wired to do) is operated. You can
also pull up on the knob shaft, which will switch
the on/on mini toggle from its "down"
position to the "up" position. Remember,
the pot and the switch are separate components,
so there is no interaction between them unless you
wire the push-pull pot to do so. Diagram #12
helps to demonstrate the lug assignment of the mini
toggle in the two positions.
As with the mini toggle switches, there is no specific
use for this component.
