Power Switches
the possibility of a breakdown of the locking function.
When designing your button, refer to the following
shape and dimensions.
Before adopting our switches, check the requirements
carefully.
Application Notes
■
When using our Power Switches, please observe the following
items (“prohibited items”) and be cautious of the following
in order to prevent dangerous accidents and deterioration
of performance.
Reference of Customer's button design
Customer's
button
1. Prohibited items and notes on mounting
1. Operation position for soldering (including preheating)
Push type switches: Do not solder in the locked condition.
Slide type switches: Be sure to switch the lever securely
when soldering.
2. When soldering using a soldering iron, soldering conditions
vary with the tip shape of the soldering iron, wattage,
and PWB thickness. Thoroughly check the conditions
in advance, including the heat resistance rating of the
solder.
3. Do not apply a load to terminals when soldering. Care
should be taken in this regard because a load may
deteriorate electric and mechanical characteristics.
4. Since the power switches are not sealed, do not wash
them.
5. When mounting a power switch to a through-hole type
PWB, the influence of thermal stress on the switch is
greater than that on one-sided PWB.

(3.0)
(0.6)
(0.6)
(3.3)
4. When mounting a switch to a set, check the switch
ON/OFF setting and the position of the operational part
(slide type, rotary type, etc.).
5. Design and use so that external stress is not
continuously applied to the soldering parts (solder lugs
and PWB terminals) with a switch mounted in a set.
6. In actual operating conditions, do not use switches
under ambient temperatures above 70 °C.
7. Avoid the following ambient surroundings and other
conditions because they may affect performance:
2
Be sure to check the influence as well as the heat
resistance rating of the solder.
Under an atmosphere of corrosive gas such as Cl ,

H S, NOx, or SO
In atmospheres of residual water drops, dew
condensation, or adhesive water drops
In liquids such as water, salt solution, oil, chemicals,
and organic solvents
2. Notes on circuit conditions
1. When a power switch is used with a weak current of less
than 500 mA, the film on the surface of contact cannot
be broken and contact failure may occur.
In direct sunlight
In dusty locations
●
●
2. The durability of power switches varies with the type
of the switch: those for ac power and those for dc
power. When using switches for ac power, check the
durability. When using switches for dc power, review
and check the load conditions of a relevant set.
3. Use the switches within their rating, including inrush
current rating. Check particularly the inrush current
using a switch with a set. Since voltage fluctuation
occurs depending on geographical region, review the
derating for using a switch.
4. Prohibited items and notes on storage conditions
Since contact characteristics and soldering quality may
deteriorate due to sulfuration and oxidation of contacts
and terminals, pay heed to the following items.
1. For storage and transport of the switches, avoid
unpacking them, and store them at room temperature
and room humidity. Use them as soon as possible,
generally within 3 months, or within a maximum of 6
months after delivery.
2. Do not store the switches under conditions of high
temperature and/or high humidity, or in a location
where corrosive gas may be generated.
3. If some units remain after unpacking, store them after
applying adequate moisture-proof and gas-proof
treatment.
4. If load conditions vary in a set to be used, adaptability
with the switch must be considered. Be sure to check
the above mentioned notes 1 to 3.
3. Prohibited items and notes on mounting and operating
conditions
1. In principle, operate the center of the lever.
2. For mounting an operation button:
1) Design so that the button is mounted to the center
5. For use in equipment for which safety requested
of the lever.
Button
Although care is taken to ensure switch quality,
variation of contact resistance (increase), short
circuits, open circuits, and temperature rise are
some problems that might be generated.
To design a set which places maximum emphasis
on safety, review the affect of any single fault of
a switch in advance and perform virtually fail-safe
design to ensure maximum safety by:
1. preparing a protective circuit or a protective
device to improve system safety, and
Lever
2) Design so that the load in removal and mounting of
the button is within the range of the switch’s strength
rating of the operational part.
2. preparing a redundant circuit to improve system
safety so that the single fault of a switch does
not cause a dangerous situation.
3. Do not pull the switch rod while it is locked. Otherwise,
the self-locking function may be broken, resulting in a
locking failure or malfunction. Make sure that the switch
is released especially when attaching/detaching a button
to the rod and assembling/disassembling the target
product. (This applies to the self-locking switches) Set
the strength for detaching your button (knob) from our
switch rod to a maximum of 10 N in order to minimize
6. For actual use, be sure to refer to “Product Specifications
for Information.”
