The Switch does not have built-in limiting resistors, so satisfy the LED characteristics by obtaining the limiting resistance according to the following formula based on the voltage to be used.
Limiting resistance (R)= (Voltage used (E) - LED forward voltage (VF)) () LED forward current (IF)

Safety Precautions
Precautions for Correct Use
Electrical Standards
All Use the Switch within the rated voltage and current ranges, otherwise the Switch may have a shortened life expectancy, radiate heat, or burn out. This particularly applies to the instantaneous voltages and currents when switching.
Handling
1. Usage Environment Before installing the Switch, make sure that the area of installation is not subject to corrosive gases emitted from surrounding parts. Do not use in areas subject to high temperatures, high humidity, or toxic gases such as sulfuric gas (H2S, SO2), ammonia gas (NH3), nitric gas (HNO3), or chlorine gas (CI2). It can cause corrosive damage to the contacts and result in malfunction. If there is silicon in the atmosphere, it may stop the contacts from functioning properly. If silicon products, such as silicon oil, silicon filler, or silicon wires, are used in the surrounding area, install a contact protection circuit to prevent arching or remove the silicon source. The following situations may cause water to enter inside the Switch, resulting in a malfunction due to contact failure or corrosion. * Using the Switch in an outdoor environment where it is exposed to water drops for an extended period of time. * Using the Switch in an underwater setting where it is subject to strong water pressure. Do not use Switches that have been dropped. The mating section or other internal parts may be damaged, resulting in malfunction.
Soldering
1. Soldering Precautions * Before any kind of soldering, test to confirm that soldering can be performed properly. Otherwise the Switch may be deformed by the soldering heat depending on the type of PCB, pattern, or lands of the PCB. * Do not solder the Switch more than twice, including rectification soldering. Wait for at least five minutes between the first and second soldering to allow the temperature to return to normal. Continuous soldering may cause the casing to melt or deteriorate the Switch characteristics. 2. Automatic Soldering Baths (Wave Soldering) * Soldering temperature: 260C max. * Soldering time: 5 s max. for a 1.6-mm thick single-side PCB * Preheating temperature: 100C max. (ambient temperature) * Preheating time: Within 60 s * Precautions Make sure that no flux will rise above the level of the PCB. Also make sure that flux is not applied to the switch terminals or to the mounting surface of the PCB. If flux overflows onto the mounting surface of the PCB, it may enter the Switch and cause a malfunction. 3. Manual Soldering * Soldering temperature: 350C max. at the tip of the soldering iron * Soldering time: 3 s max. for a 1.6-mm thick, single-side PCB * Precautions: Before soldering the Switch on a PCB, make sure that there is no unnecessary space between the Switch and the PCB.
Operation
Do not repeatedly operate the Switch with excessive force. Applying excessive pressure or applying additional force after the plunger has stopped may deform the disk spring of the Switch, resulting in malfunction. Be sure to set up the Switch so that the plunger will operate in a straight vertical line. If the plunger is pressed off-center or from an angle it may cause deformation or damage to some parts. This may result in deterioration of durability or malfunction.
Washing
Since Illumination part and actuation part are not sealed, switch cannot be washed. Doing so will cause the washing agent, together with flux or dust particles on the PCB, to enter the Switch, resulting in malfunction.
PCBs
The Switch is designed for a 1.6-mm thick, single-side PCB. Using PCBs with a different thickness or using double-sided, through-hole PCBs may result in loose mounting, improper insertion, or poor heat resistance in soldering. These effects will occur, depending on the type of holes and patterns of the PCB. Therefore, it is recommended that a verification test is conducted

Removing the Cap - Text Film Installation
1. Hold the cap at the side away from the mating section. Pull straight up. 2. Do not remove the cap while the Switch is mounted. Doing so will apply force to the soldered section and LEDs, resulting in malfunction.
Dust Protection
Although the switching mechanism is a sealed structure (IP64), illumination part and actuation part is not sealed. Ensure you have the correct environmental conditions for installation. Use a protective sheet or take other measures to protect against dust.
Sensitivity to Static Electricity
Switches with high-brightness green (HG) or blue (B) LEDs are susceptible to static electricity. Take care when handling switches with these LEDs as the LEDs may be damaged.
Storage Precautions
Storage Environment To prevent degradation, such as discoloration, of the terminals during storage, do not store the Switch in locations that are subject to the following conditions. 1. High temperature or humidity 2. Corrosive gases 3. Direct sunlight Storage condition Store the Switches in the packaging box. After the packaging box is opened, use the contents as quickly as possible. When storing leftover parts, make sure that appropriate measures are taken against humidity and corrosive gases.
Correct
Incorrect
Placing the Cap on the Switch
Hold the Cap at the side away from the mating section. Push straight down until the mating section meets.
Agreement of Product Use
Comply with the usage, storage, and disposal conditions specified by OMRON as outlined in the precautions in the product datasheet and specifications.
Correct
Incorrect
Removing the Cap
The Cap can be removed up to two times. Excessively removing the Cap will cause the mating section to become weak, resulting the operating section not mating completely or the Cap may fall off.
Be sure to read the precautions common to all Tactile Switches, contained in the Technical User's Guide, "Tactile Switches, Technical Information" for correct use

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given: (i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document. (ii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations. (iii) Use in consumer products or any use in significant quantities. (iv) Systems, machines and equipment that could present a risk to life or property.

Programmable Products. Seller shall not be responsible for the user's programming of a programmable product, or any consequence thereof. 3. Performance Data.

Product specifications and accessories may be changed at any time based on improvements and other reasons.

Please consult with your Seller representative at any time to confirm actual specifications of purchased Product. 5. Errors and Omissions.
