NOTES
1. Dustproof, waterproof,
2. Installation
e. If the rubber cap is installed over the
anticorrosive gas, and oil-proof
designs
1) For the toggle and push-button type
a. When installing the standard type
switch, be sure to use a hex nut.
b. For the panel-sealed, terminal-sealed
and wire lead types, use a lock washer
on the front side of the panel, and an
O-ring on the back side of it.
hex nut, the waterproof performance will
be impaired although the dustproof
performance will not be affected.
The panel-sealed type/terminal-sealed
type/wire lead type switch has a
protection level of IP67 on the outer side
of the mounting panel and a level of IP40,
IP60, or IP67 on the inner side of the
panel.
For actual application, note the following
points:
1) Avoid immersion in water or oil during
installation.
c. Do not install the switch by rotating it.
2) For the rocker type
Hexagonal nut
a. In case the panel-sealed, terminal-
sealed or wire leads types are used in the
condition where the water splash on,
please install the switches tilt more than
25°. (90° recommended)
2) Avoid immersion in water or oil during
operation.
3. Soldering
3) Oils or gases impose varying degrees
of impact on the switch’s sealing
performance depending on type or
quantity.
1) By using 350°C soldering iron,
soldering should be completed within 5
seconds.
2) Exercise care so as not to touch the
switch body with a soldering iron.
4. Load type and ratings
1) When the switch is loaded with a lamp,
motor or capacitive load, a surge current
higher than the stationary current passes
through the switch contacts.
Measure the surge with the actual load
and, if needed, take necessory action so
that the surge will not exceed the switch’s
rated current.

4) While the switch has a immersion and
dust-protected design, its sealing
performance or operabillity may be
adversely affected in an environment
where in the switch's movable parts can
be contaminated with dust, oil, or other
foreign objects. For the toggle type, use
of a rubber cap is recommended.
5)The standard toggle switch, when used
with a rubber cap, provides a protection
level of IP54.
b. In case water inside the switch case
may freeze, please install the switch
vertically to avoid the water remain inside
the switch.
2) When the switch is loaded with an
inductive load (relay, solenoid, buzzer,
etc.), a contact failure may result from arc
discharge caused by a
It should be used in an environment
where it will not be subject to frequent
water splashes.
3) Rubber cap installation
6) As the sealing performance of the
rocker type switch is affected by the panel
processing accuracy or mounted panel
thickness, check the switch under actual
loading conditions. (While water or dust
will not enter the switch’s internal
structure, it may enter the panel.)
7) Do not operate the rocker type switch
when water accumulates in the switch
handle.
a. The washer should be used on the
back side of the panel.
counterelectromotive force. It is advisable
that you use an adequate anti-spark
circuit across the switch contacts.
5. Others
1) Do not apply an excessive static load
exceeding 112.7N {11.5kgf}
perpendicular to the direction of
operation.
2) Operate the switch knob by hand.
3) Take care not to drop the product as it
may impair performance.
3.0 to 3.5 mm

b. Enough screw pitch should be
obtained being adjusted within 3 to
3.5mm (See Fig.2)
c. Install a rubber cap on the switch knob
before securing the switch with the hex
nut.
d. The mounting hole in the panel should
preferably be provided with an anti-
rotation projection.
