Precautions for Correct Use

●Wiring

·The rough standard for soldering work is as follows.

·Capacity of soldering iron: 60 W
Soldering time: 3 sec max.

●Washing

·The 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.

●Application / Storage Environment

·Do not use the Switch in locations that are subject to toxic gas, silicon, excessive dust, excessive dirt, high temperatures, high humidity, sudden temperature changes, water splashes, or oil splashes.
Otherwise, damage resulting by contact failure of the Switch contacts, corrosion, or other causes, or other functional failure may occur.

·The operating characteristics, contact resistance, insulation resistance and dielectric strength of the Switches should be inspected before the usage, if there is the following conditions;

·If they are stored more than 1 year after the production.

·If they are fallen down.

·If condensation occurs.

·If they had been left out of the storage environmental conditions.
