Precautions

■ Precautions for Correct Use

Storage

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;

• High temperature or humidity

• Corrosive gases

• 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.

Handling

Usage Environment

Before installing the Switch, make sure that the area of installation is

not subject to corrosive gases emitted from surrounding parts.

1. Do not use in areas subject to high temperatures, high humid-

ity, or toxic gases such as sulfuric gas (H

gas (NH

cause corrosive damage to the contacts and result in mal-

function.

2. 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 Switch is not completely

sealed. 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 sub-

ject to strong water pressure.

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. (Maximum force = 30N)

• 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 life expectancy or malfunction.
