Ordering Information
Switches (Single Switch Units)
Note: 1. The classification diagrams show 4 Switch Units combined with End Caps to create 4-digit displays.
2. The model numbers given above are for 1 Switch Unit.
3. Models with stoppers are also available. Add “-S@@” after the “203,” “206,” “207,” “219,” “254,” or “255” in the model number and specify the display range in
the @@. For example, to specify the range 0 to 6, add “-S06” to the model number (e.g., A7PS-206-S06-1).
“-SOF” can not be available for type -254, -255.
4. Models with +, - displays can also be produced. Add “-PM” after the “206” in the model number (e.g., A7PS-206-PM or A7PS-206-PM-1)
*1. Models with diodes are available. Add “-D” to the model number (e.g., A7PS-207-D or A7PS-207-D-1).
Accessories (Order Separately)
Use accessories, such as End Caps and Spacers, with the Switch
Units.
Note: The @ in the Spacer model number stands for a letter in the range A to
U. (Refer to the table in the following explanation about Spacers.)
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.

Output Codes/Terminals
•Switches with output codes 06 or 07 both
use binary coded decimal but Switches
with output code 07 have a component-
adding provision. Similarly, Switches
with output codes 54 or 55 both use
binary coded hexadecimal but Switches
with output code 55 have a component-
adding provision.
•How to Read Output Codes
For example, when the dial position is
“3,” the common terminal C on the
Switch is connected to terminals 1 and 2.
When the Switch is inserted into the
Connector, the common terminal C
becomes connector terminal 3, and
terminals 1 and 2 become connector
terminals 5 and 7 respectively.

Ordering Procedure
Place orders as shown in the example below, specifying the model and number.
Safety Precautions
Refer to Precautions for Correct Use on in the Technical Guide for Thumbwheel Switches.
Handling
•The molded components of the Switch use polyacetal resin and
ABS 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.
•A7P Thumbwheel Switches are dust-proof, but they are not drip-
proof. Do not use them in areas subject to water or oil exposure.
•Do not allow solder flux or alcohol to enter the Switch.
•
Do not push the (+) and (-) operating push-buttons at the same time.
•
To separate the Switches, use a flat-blade screwdriver as shown in the
following figure to release the hooks on the top and bottom and then
separate the Switches. Be careful not to bend the hooks.
