Precautions for Correct Use
Storage
Storage Environment
To prevent degradation, such as discoloration, in the terminals
during storage, do not store the Switch in locations that are sub-
ject 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.
Handling
Usage Environment
Before installing the Switch, make sure that the area of installa-
tion is not subject to corrosive gases emitted from surrounding
parts.
1. Do not use in areas subject to high temperatures, high
humidity, or toxic gases such as sulfuric gas (H
2
S, SO
2
),
ammonia gas (NH
3
), nitric gas (HNO
3
), or chlorine gas
(CI
2
). It can cause corrosive damage to the contacts and
result in malfunction.
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 situa-
tions may cause water to enter inside the Switch, resulting
in a malfunction due to contact failure or corrosion.
