Omron offers two economical solutions for long-term maintenance of D4A-N limit switches. Choose a complete switch body with a built-in
switch, or just replace the internal switch by removing the two screws holding it in place.

The D4A-N family of switches features
plug-in construction with interchangeable
parts for simplified long-term maintenance.
The illustration at right shows the parts that
make up a whole switch, as well as how to
read a part number as the sum of its parts.
Note: Compatibility of D4A-N parts with
Omron's former D4A series is limited to
interchangeable receptacles only. D4A
switch bodies and operating heads cannot
be used to replace similar D4A-N parts.
