End Caps
End Caps are used on the Switch Units at each end and allow all the Switch Units to be securely mounted to a panel. They come in pairs, one for
the left and one for the right.
Spacers
• Spacers are used for creating extra space or gaps between the Switch Units and have the same dimensions as the Switch Units themselves.
• There are also Spacers with engraved characters or symbols that can be used for indicating units, such as time and length. (Refer to the following
table.) Consult your OMRON representative for details.

Safety Precautions
Refer to Precautions for Correct Use on in the Technical Guide for Thumbwheel Switches.
Precautions for Correct Use
Environment
Screw-mounting Models
• Do not use where gases are generated (ammonia, chlorine, sulfur
dioxide).
Tighten mounting screws to a torque between 0.2 to 0.24 N·m, using
M2.6 screws. Use plain washers or spring washers together with the
screws.
• Although Switches are of nearly dust-proof construction, they are
not drip-proof, therefore do not use in areas subject to water or oil
exposure and do not operate with wet or oily hands.
• Provide additional dust-proofing measures, such as using a dust-
proof cover, when using in sand-exposed areas.
Setting Numbers
Locking Type
• Set with the setting button by raising it.
Do not
push here
• Return the button to its original position
after setting. It is then locked to prevent
rotation, and the set numbers will not
change accidentally.
Handling
• The A7CN cannot be connected to the A7C.
• The molded components of the Switch use polyacetal resin and
polycarbonate resin. It is recommended that alcohol is used to wipe
off dirt and smudges from the molded components. Take care to
prevent the alcohol from getting inside.
Do not use thinner or other solutions which might damage the resin.
• When changing settings, do not touch the operating buttons if your
fingers are wet or there is oil or any other foreign substance on your
fingers.
Soldering
Note the following points when soldering
printed circuit boards:
• The terminal insertion holes on the PCB must be at least 1 mm in
diameter.
• Automatic Soldering
Do not use dip cleaning. Doing so may result in flux penetration of
the Switch interior, causing contact and rotational defects. Clean
the flux as shown in Figure 1, tilting the Switch 80° or less and using
a brush to apply the solvent only to the back of the board. It may
also be cleaned by dipping only the back of the board into the
solvent and then using a brush to clean.
• Do not drop the individual Switches. Doing so may damage the
resin catch (for connecting) on the side of the Switch.
• When separating Switches, use a screwdriver as shown in the
figure below; disconnect them by releasing the top and bottom
hooks. Be careful not to bend the hooks.
• Dip Soldering
When applying flux solvent, the dipping time is a maximum of 2
seconds. As shown in Figure 2, avoid flooding the top surface of the
printed circuit board with flux. Using a brush to apply flux further
reduces the danger of flux penetration. When cleaning flux with a
brush, tilt the Switch 80° or less, as shown in Figure 1, in order to
prevent flux from flowing onto the switch mounting surface. Clean
flux as described above under Automatic Soldering.
Figure 1
Figure 2
• When connecting Switches, fit the mating parts together.
• Do not push the (+) and (-) operating push-buttons at the same
time.

Back surface
of board
Models with PCB Terminals
Do not use excessive force in handling the Switches. In particular,
take care to avoid dropping them because the terminals might bend
or break.
Wipe away flux
with a brush.
80° or less
• Using a Soldering Iron
Use a 30-W soldering iron at a temperature of 350°C for a
maximum of 3 seconds, and flush as described above.
Do not apply force to the terminals during soldering and for 3
minutes after soldering is completed. Doing so may result in
conduction or operation failure.
• Ensure that soldering flux and alcohol do not penetrate into the
Switch interior

The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
·
·
Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
Nuclear 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.
·
Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.

Disclaimers
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 model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
