Precautions
■ Correct Use
■ Cautions
Mounting
Do not wire the Switch or touch any terminal of the
Switch While power is being supplied. Doing so may
result in electric shock.
Turn OFF the power supply before mounting, removing or wiring the
Switch, or before performing maintenance inspections. Failure to do
so may result in electric shock.
Do not use panels other than ones with the designated thickness and
dimensions. Remove all burrs from the cutout before installing the
Switch. Otherwise, the Switch may malfunction.
Do not impose excessive force on the Switch at the time of panelmounting.
There are two small divots in the flange part of the case marking ON
and OFF as shown in the following diagram. Use these marks as
guides when mounting.
OFF
ON
Wiring
When soldering terminals manually, perform soldering within 3 s
using a 60-W soldering iron (temperature at the tip of the soldering
iron: 420°C max.). Do not apply excessive force to the terminals during soldering.
When soldering using a soldering tub, perform soldering within 5 s in
a soldering fluid at 270°C, or within 3 s in a soldering fluid at 350°C.
Be sure that the wires are thick enough for the load (current) to be
applied.
Only A8L-@@-@5@@ models are equipped with (6.3×0.8) mm flatquick connections for use with #187 fasten receptacles.
The terminals of A8L-@@-@1@@ are not in compliance with IEC
standards for flat-quick connections. Suitable for use as solder connection only.
Using Microloads
The performance of the Switch may be affected if the Switch is used
for switching micro loads. Test the Switch under the actual operating
conditions.
Operating Environment
Do not use the Switch in places with sulfide gas, corrosive gas, sea
breeze, oil spray, or direct sunlight. Otherwise, the Switch may malfunction.
Do not use the Switch in places that are visibly dusty. Otherwise, the
contacts may fail to operate correctly.
4
Miniature Rocker Switch
A8L
To increase the reliability of operation, test the Switch before actual
operation.
Be sure that there is an enough insulation distance between any
Switch terminal and metal part.
Handling
Do not drop the Switch. Otherwise, the Switch may malfunction.
Do not impose excessive force on the Switch. Otherwise, the Switch
may deform.
The recommended panel material is SPCC. The Switch may fall off if
the material is soft and cannot securely hold the Switch. When using
a soft material, test the Switch with it before using the Switch in
actual operation.

Certain Precautions on Specifications and Use
1. Suitability for Use. Seller shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the Product in
Buyer's application or use of the Product. At Buyer's request, Seller will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not
sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use.
Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer's application, product or system. Buyer
shall take application responsibility in all cases but the following is a nonexhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government
regulations.
(iii) Use in consumer products or any use in significant quantities.
(iv) Systems, machines and equipment that could present a risk to life or
property. Please know and observe all prohibitions of use applicable to this
product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE SYSTEM
AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT
THE OMRON PRODUCT IS PROPERLY RATED AND INSTALLED FOR THE
INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Seller shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
3. Performance Data. Performance data given in this publication is provided as
a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Seller's test conditions, and the users must
correlate it to actual application requirements. Actual performance is subject to
Seller's Warranty and Limitations of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Seller representative at any time to
confirm actual specifications of purchased Product.
5. Errors and Omissions. The information in this publication has been carefully
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors, or omissions.
6. RoHS Compliance. Where indicated, our products currently comply, to the
best of our knowledge as of the date of this publication, with the requirements
