Enabling Grip Switch with Distinct Feel
for Three Easily Discernible Positions
• In addition to the standard models, the lineup also includes
models with an emergency stop switch and models with a
momentary operation switch.
• An optional Holding Key (sold separately) provides a versatile
method for selecting modes.
• Equipped with conduit connector.
Be sure to read the
“Safety Precautions”
on page 10.
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Features
Positive Operating Feel
Original Double Snap Action switch mechanism lets the operator
precisely confirm the enable position.
Safety Circuits Are Easy to Configure
Safety circuits can be easily configured by combining the A4EG with
the G9SX-GS Safety Guard Switching Unit.

Safety Key Selector Switch
A22TK
Single-press design ensures a
positive click feel when only one
part of the switch is pressed, to
enable positive confirmation.
The Selector Switch can be used to switch between
normal operating mode (using the Door Switch) and
maintenance mode (using the Enabling Grip Switch).
Selection Based on Application
In addition to the standard models, the lineup also includes models
with an emergency stop switch and models with a momentary
operation switch.
