The two-spring socket (?1) just has two springs, and won’t do
anything by itself. It is not used in any of the experiments. It was
included to make it easy to connect other electronic components to
your Snap Kits
TM . It should only be used by advanced users who
are creating their own circuits.
There are many different types of electronic components and basic
parts, like resistors and capacitors, that have a wide range of
available values. For example, your Snap Kits
TM includes five fixed-
value resistors (100 Ω, 1KΩ, 5.1KΩ, 10KΩ, and 100KΩ). This is a
very limited choice of values, and difficult to design circuits with.
Your Snap Kits
TM also includes an adjustable resistor (RV), but it is
difficult to set this part to a particular value. You can place your
resistors in series and parallel to make different values, but this is
also difficult with only five values to choose from.
The two-spring socket (?1) makes it easy to connect your own
resistors (and other parts) to circuits by connecting them between
the springs:
Any component with two wires coming from it (called leads) can be
connected with the two-spring socket (?1), assuming the leads are
long enough. Usually you will connect different values of resistors
or capacitors, but other components like LED’s, diodes, or
coils/inductors can also be used. You can usually find electronic
components at any Radio Shack store.
You can design your own circuits or substitute new parts into the
projects in the manuals. For LED’s, diodes, or electrolytic
capacitors, be sure to connect your parts using the correct polarity
or you may damage them. Never exceed the voltage ratings of any
parts. RADIO SHACK IS NOT RESPONSIBLE FOR ANY PARTS
DAMAGED BY IMPROPER CIRCUIT DESIGN OR WIRING.
Never connect to external voltages. The two-spring socket is
only intended for advanced users.
