3. In
this
circuit,
we
demonstrate
the
use
of
relay
as
a
switch.
To
control
an
ordinary
switch,
one
needs
to
mechanically
do
work
to
make
it
ON/OFF.
Imagine
what
if
we
can
control
the
switching
acFon
using
voltage
(supply).
The
relay
is
an
electromagneFc
switch
and
a
perfect
example
how
we
can
use
the
electromagneFc
force
to
switching
acFon
of
any
switch.
The
system
is
composed
of
a
relay,
two
LEDs
and
two
9V
baNeries.
When
no
external
supply
is
given
to
the
relay,
the
LED
connected
to
its
NC
terminal
glows.
However,
when
the
supply
is
given,
the
LED
connected
to
the
NO
terminal
glows
and
the
LED
connected
to
the
NC
terminal
gets
OFF.
