Precautions for Correct Use

●Electrical Standards

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.

●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: 260°C max.
•Soldering time: 5 s max. for a 1.6-mm thick single-side PCB
•Preheating temperature: 100°C 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: 350°C 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.

●Washing

Standard Switches are not sealed, and 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 before use.

●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.

●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 of-center or from an angle it may cause deformation or damage to some parts. This may result in deterioration of durability or malfunction.

●Dust Protection

Do not install or use Switches in dust-prone environments. If a Switch must be used in this kind of environment, use a protective sheet or take other measures to protect it against dust.

●LEDs

Switches with high-brightness green (HG) or blue (B) LEDs are susceptible to static electricity. Be careful when handling a Switch with these LEDs as it may cause the Switch to breakdown.

●Removing the Cap

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.

●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.

●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.

●Film Dimensions

Dimensions of the film are shown below. The thickness is 0.2 mm.
