PRECAUTIONS FOR CORRECT USE
1. 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.
2. Wait for one minute during and after soldering before exerting any external force on the solder.
3. The rated voltage is shown on the resistor board and on the side of the light cartridge, so be sure before use.

4. Character films are not included.
If preparing the character film separately, use a heat-resistant film with a thickness of 0.1 mm.

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.
