Safety Precautions
Refer to the “Precautions for All Switches” on page I-2 and “Precautions for All Safety Door Switches” on page A-2.
■ Precautions for Safe Use
• Never disassemble or modify your D4NS in any way, or the D4NS
• Do not use the Switch submersed in oil or water or in locations
• Although the switch body is protected from the ingress of dust or
• Always be sure that the power supply is turned OFF while wiring
• Always attach the cover after completing wiring and before using
• Connect a fuse in series with the D4NS to protect it from short-
• When switching general loads (250 VAC/3 A), do not operate two
Stopper Installation
Do not use a Switch as a stopper. Be sure to install a stopper as
shown in the following illustration when mounting the Switch so that
the base of the Operation Key does not strike the Head.
■ Precautions for Correct Use
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.

continuously subject to splashes of oil or water. Doing so may result
in oil or water entering the Switch. (The IP67 degree of protection of
the Switch specifies the amount of water penetration after the
Switch is submerged in water for a certain period of time.)

on the head.
Otherwise, accelerated wear or breaking may result.

the cover attached.
circuit damage. The value of the breaking current of the fuse must
be calculated by multiplying the rated current by 150% to 200%.
When using the D4NS for an EN rating, use a 10-A fuse of type gI
or gG that complies with IEC 60269.
