PRECAUTIONS FOR CORRECT USE
1．Solder quickly and correctly at 350℃ max. and for 3 seconds or less. Be careful not to touch the soldering iron to the main body.
2．Wait for one minute during and after soldering before exerting any external force on the solder.
3．Character films are not included. If preparing the character film separately, use a heat-resistant film with a thickness of 0.1 mm.
For dimensions, please refer to the figure below.
00

6.6 －0.2

10.5 －0.2

4．No built-in LED protection resistor and LED cannot be replaced.
5．HH is flux-prevention, but that is only terminal part. Take care to prevent flux from penetrating the sliding parts.

※ For handling instructions and precautions other than the above, please refer to “Safety Precautions for All IlluminatedPushbutton Switches”.

regarding special damages, indirect damages, incidental damages, or passive damages that occurred due to Sunmulon product.

4. Handling precautions for switch(1) Do not perform wiring with power supplied to the switch. Do not touch the terminals or other charged parts of the switch while power is being supplied.
Doing so may result in electric shock.
(2) Be careful of electrostatic breakdown when handling.
(3) Do not drop or otherwise apply strong force to the switch.
(4) Do not place heavy objects on the switch.
(5) Do not operate or use the housing (switch unit) by itself. Use the switch with assembled the illuminated part (LED module or button).
(6) Pushbutton switches are designed to be operated by fingertips. Operating the switch using a sharp object (screwdrivers, tweezers, etc.), hard object(metal, etc.), or with a large or sudden force, may cause deform or damage the switch.
(7) Do not use the switch under loads that exceed the rated switching capacity or other contact ratings. Doing so may result in welding of the contact,or burnout accidents.

(c) When wiring, pay attention to the polarity of the terminals.
(d) Simultaneous lighting may not be possible with Dual-Color illumination or Split-Face illumination (2, 3, or 4 split illumination), check the catalog.
(e) Apply voltage directly to LEDs of Non-built-in resistor type will damage the LEDs, so connect an appropriate external resistor.

(11) Wiring(a) Do not apply a soldering iron to the switch housing. Doing so may deform the terminals and cause defects.
(b) See catalog for models compatible with flux prevention measures terminal. Be careful not to allow flux to panetrate sliding parts such as buttons.
Use non-corrosive rosin solution as flux for dip soldering.
(c) For soldering other than flux-preventive models, hand solder with the terminals facing down to prevent flux from penetrating into the switch.

Correct

Incorrect(d) The housing of KA, K2, and K9 series are designed for reflow soldering.
(e) Use the appropriate wire size for the applied voltage and current, and solder properly. Use of the product with incomplete soldering may cause
abnormal heat generation, resulting in a fire hazard.
(f) After wiring is completed, maintain an appropriate insulation distance.

PRECAUTION-2

Safety Precautions for All Illuminted Pushbutton Switches(12) Usage environment(a) Do not use in the presence of flammable or explosive gases such as gasoline, thinner, LPG, etc.
(b) Avoid using the product in places where corrosive or silicon gas is generated, high temperature, high humidity, sea breeze or direct sunlight.
(c) Provide appropriate protection when using the product in places where it is exposed to water, oil, metal powder, or dust.
(d) Do not use the product in a place subject to vibration or shock. It may cause malfunction or damage.
(e) When installed in a close grouping or continuously lit, the ambient temperature may exceed the specified value due to heat generation.
Take measures such as ventilation and lowering the operating voltage.
(f) When checking the actual equipment, load conditions and operating environment should be the same as the actual operating conditions.
(g) The ambient temperature for storage is －25℃ to 65 ℃ (No freeze, no condensation).

(13) When wiping off dirt on the exterior of the switch and accessories such as side plates, wipe lightly with a soft, dry cloth. Organic solvents such as
thinner, benzene, alcohol, or other acidic chemicals may cause deformation, discoloration, or malfunction.
(14) Store the product away from malignant gases, dust, high temperature and high humidity, and keep it in our packing condition.
(15) When removing the illuminated part (or button) from the alternate switch housing, switch state should be in a free state.

Correct

Incorrect

Removal in a locked state may cause malfunction or damage
to alternate switch.

(Button)Free state

Locked state(16) Periodic inspection and replacement(a) Although mechanical and electrical durability are listed in the specifications column, deterioration of various parts (deterioration of resins andcorrosion of metal parts) is possible due to the operating environment and method of use. We ask that you implement inspections for Sunmulon
products to prevent accidents from occurring by conducting periodic inspections and replacements.
(b) When the switch is left unused or stored for long periods, contact reliability may deteriorate due to oxidation of contacts, which may cause continuity
failure, etc. Therefore, it is necessary to check the operation before use.
