More than 50% reduction of mounting cost comparing to DIP type.

Surface-Mountable Terminals (SMT) switch can be mounted directly by mounting machine
as same as other surface-mounted component.

SMT switches can be precisely mounted, so it's unnecessary to correct or repair

of slanting and twisting.

Additionally, It has not protrusive terminals on the reverse side of printed-circuit board,
it's unnecessary cutting work of the terminals.

It can achieve significant mount working time reduction from traditional manual fabrication.

Working time of mounting operation per- SMT switch (18sc/pc) can reduce more than 50%
from DIP switch (38 sec/pc). ※The data form the calculations of our own.

*No need of modification by hand working after SMT.

*Most suitable for overseas production because of automated way.

Not only cost but also quality will be improved by SMT.

　　　　Sunmulon SMT switch 　　　　　　　　　　 Usual DIP switch

DIP switch often need to correct or repair of slanting and twisting, cutting work of the terminals after mounted.

Please see the surface-mounting process movie.

①Print the solder paste on the printed circuit board.

②Up to 96 units of switch block are put in the dedicated tray.

If ordered 32 units or more, the order will be delivered in a tray.

③Mount the switch block to the printed circuit board from tray by mounting machine.

④Dissolve the solder paste with the reflow soldering machine
and finished soldering.

Slanting and twisting during mounting does not occur by our own know-how.

You can align switches in a straight line without particular modifications.

⑤Peel off a heat-resistant sticker from switch block,
and then assemble with the lighting block.

Easy to assemble by modular switch concept, composed of
switch block and lighting block.

　⑥Surface-mounting finished.

Stable active position,Long operating life,Smooth operating feeling.
