PRECAUTIONS FOR CORRECT USE
1．For types with N (Neutral) such as M-N-M, chattering may occur due to inertia of the switch when one side is turned ON
and the hand is released to return to N. (For A, when the other side is pushed.)
In such cases, please install an anti-chattering circuit. (Refer to diagrams below.)

2．For A-N-M and A-N-A, when returning the alternate to N, be sure how to push, as pushing the other side too hard may cause
the other side to operate without activating N.
3．When using for CPU or other devices with high-speed responsivity, please install an anti-chattering circuit. (Refer to diagrams above.)
4．Solder quickly and correctly at 380℃ max. and for 3 seconds or less. Be careful not to touch the soldering iron to the main body.
5．Wait for one minute during and after soldering before exerting any external force on the solder.
6．The rated voltage is shown on the side of the LED unit, so be sure before use.

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.

(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.
