KA, K2, K9 SMT-compatible Illuminating Switch

SMT
series

Surface mounting (SMT) made possible in a world firstfor illuminating push-button switches

Maximum 70% reduction in installation costs! Improved installation quality!
■Helps reduce costs with a reduction in installation costs at the time of domestic production.
■Provides stable quality due to installation by machines at the time of overseas production.
■Reduces the tilts and twists at the time of mounting by utilizing original know-how to dramatically improve
mounting accuracy.
Also, there is no need for twist adjustments after mounting, so work efficiency will be increased drastically.
■Provides a smooth operational feel due to the introduction of the ball bearing structure (KA, K2)■KA provides clear click feedback with a maximum 45% of the click rate.
K2 achieves a maximum 30% of the click rate, and K9 a maximum 20% of the click rate.
■Easy assembly of parts including button, filter, light cartridge, and main body.
■Smooth and easy assembly at the time of writing name on the illuminating side
■Easy replacement of the light cartridge due to the structure that separates the mainContact form
body and the light cartridge.
■Features:
KA: High frequency, high durability, and high click rate to provide clear click feedback
K2: Allows highly dense installation, and provides the same level of performance as KA.
K9: For a 9 square button only

SOLDERING SPECIFICATIONS*Soldering(1) Conduct preliminary testing for confirming the soldering conditions.
Switches could be deformed by heat depending on the baseboard type, pattern and round.
(2) Perform soldering no more than twice, including corrective re-soldering.
When soldering repeatedly, wait at least five minutes between the first and second soldering until the work cools to room temperature.
Continuous heating can result in deformity of outer contours and deterioration.

*Recommended conditions for reflow soldering (when attaching single terminal)
Fix a thermocouple on the side of the terminal using a high melting point solder (high-temperature adhesive), and set a reflow furnacereferring to the temperature profile example shown below for the terminal temperature. Deformity could result due to the heat if the
product temperature exceeds 260C,therefore ensure that the temperature on the product surface remains below 260C.
Preliminary heating: 150C to 180C
60-120 sec
Actual heating : 220C or above
Within 30-60 sec
Solder type : Sn96.5
Ag3
Cu0.5
*A30C5 (JIS indication)[Temperature profile example when lead-free solder is used]

250C
220C
180C
150C

* Consult with us if you wish to attach parts
continuously or in high density.

60 ~ 120s

60s max*Manual soldering(1) Soldering temperature: 350C or less at tip of solder applicator(2) Soldering time: within 3 sec*Cleaning
The switches may not be washed.
Washing may cause flux and foreign matter on the baseboard to get inside the switch along with detergent, and could cause failure.

*Printed baseboard(1) Resistance to soldering heat could be affected depending on the type, thickness and round pattern of the printed baseboard.
We recommend confirming the volume-production conditions of the printed baseboard beforehand.
(2) Handle the baseboard carefully after attaching the switches.
Scattered powder from baseboards could get inside the switch while separating the baseboard.
Avoid piling printed baseboards.

HANDLING PRECAUTIONS*Handling of switches(1) Usage environment
Prior to setting the product in the environment for actual usage, check that no corrosive or other gas is emitted from component parts in the vicinity.
Avoid using in atmospheres containing sulfidizing gas (H2S, SO2), ammonia gas (NH3), nitrate gas (NH3), chlorine gas (CL2) or other corrosive gases, orunder high temperature or humidity.
(2) Contact errors could result if silicon is present in the vicinity of the switch.
Remove the source of silicon if silicon oil, silicon filler, silicon wire or other silicon products are present around the switch.
(3) Dust-prevention measures
Avoid using the switches in places where dust is generated.
(4) Waterproofing and drip-proofing
The switches are not waterproof or drip-proof. Avoid installing or using them in places where they might be splashed with liquids.
(5) Automatic mounting
The switches can be mounted automatically on baseboards, but this may not be possible with some types of mounting machines. We recommend checking
beforehand when using the product this way.
(6) Strength of terminals
Note that if a terminal is bent or twisted, its strength declines and the terminal could break.

*Matters for caution when storing(1) Storage environment
When storing the product, please take full consideration that the atmosphere, humidity and other storage conditions could affect the ease of soldering ofterminals and packaging functions.
-Packaging material is expected to age more rapidly under high temperatures and humidity. We recommend storing the products indoors at temperatures
up to 25C and relative humidity up to 50%.
-Avoid storing the products in an environment with sulfidizing or other corrosive gases.
-Avoid direct sunlight and dust.
(2) Storage conditions
Store the products in the packaging.
Use products promptly after opening the packaging, and store the remaining products in an area
free of gas, humidity and other factors which might affect performance.
