BL-Series
Our
BL-Series
metal
tactile
domes
are
four-legged
switch
contacts
that
were
designed
for
mounting
on
single
or
double
sided
printed
circuit
boards,
flex
circuits
and
membranes,
where
traces
can
be
fed
under
the
domes
on
the
same
side
of
the
board.
What
differentiates
the
BL-Series
domes
from
other
four
leg
metal
domes
is
the
hole
in
the
center
of
the
dome.
The
hole
allows
for
the
placement
of
an
LED
directly
behind
the
dome
switch
rather
than
off
the
side.
The
result
is
more
intense
lighting
effect.
Applications
requiring
a
back-lit
switch
with
extensive
tactile
feedback
are
a
perfect
fit
with
the
BL-Series
domes.
The
BL-Series
domes
come
in
three
different
sizes,
and
can
be
used
anywhere
a
momentary
switch
with
tactile
feedback
is
required,
while
still
achieving
impressive
actuation
life
cycles.
The
BL-Series
domes
are
placed
on
a
PC
board
by
means
of
pressure
sensitive
adhesive
tape.
In
their
relaxed
state
they
rest
on
the
outer
rim
of
the
primary
pathway.
When
they
are
pushed,
the
centers
of
the
domes
collapse
and
make
contact
with
the
secondary
pathway,
thereby
closing
the
circuit. |
