Switch
production
is
made
at
one
time
according
to
the
final
membrane
switch
design.
The
connection
of
the
switch
group
and
the
lead-out
of
the
switch
circuit
have
been
screen
printed
at
one
time
by
special
printing
methods.
In
terms
of
the
cost
of
switch
processing,
the
cost
is
lower
than
that
of
discrete
parts
especially
for
large-scale
manufacture.
In
terms
of
the
overall
cost
of
the
user,
it
also
has
these
economic
advantages.
Firstly, there is no need of punching and fixing, which greatly reduces the assembly process. Secondly, the connection of the switch group does not need to be welded one by one. It can not only save time but also avoid the hidden trouble caused by welding quality. Thirdly, there is no need to configure the panel, dig holes and open windows on the display part of machine interfaces. At the same time, due to the innovative structure and strong sense of the times, it can improve the credibility and market competitiveness of products. of course, the added value generated is still obvious.
