A world first in surface-mountable illuminating pushbutton switch

Switch with features new and never before seen

KA series

K2 series

K9 series

Innovative Surface-mountable terminals switch(SMT).

Surface-mountable terminals 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.

　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.

Reduction in mount working cost of more than 50%

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

SMT switch		DIP switch
Mounted 31 pcs by mounting machine	11 sec/pc	Masking	13 sec/pc
		Alignment	10 sec/pc
		solder bath in flow soldering	4 sec/pc
Peal off a heat-resistant sticker from the switch block and assemble the lighting block .	7 sec/pc	Retouch for slanting and twisting parts.	11 sec/pc
	18 sec/pc		38 sec/pc

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.

KA, K2, K9 Series Features

Advantage of SUNMULON SMT switch

*Heat resistant switch block for SMT production.

*Accurate mounting layout after SMT.

*No need of modification by hand working after SMT.

*Most suitable for overseas production because of automated way.

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

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

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.

Please see the surface-mounting process movie.

Evaluation units for surface mounting are available(charged).
