Safety Key Selector Switch
A22TK
Key-type Selector Switch with Direct
Opening Mechanism
• Selector Switch for secure equipment activation during
maintenance
• 30 types of exclusive keys make it more difficult to disable.
• The trapped key of the D4JL Guard Lock Safety-door Switch has
the same shape as the lockout key of the D4GL-SK10-LK Slide Key
Unit. Units can be combined to improve safety.
(Specify the same key type.)
• Common to the switch part of Emergency Stop Switch A22E.
(Non-lighted model only)
For safety precautions for all pushbutton switches, refer to the website
at: www.ia.omron.com, and “Safety Precautions” on page 12 in this
catalog.
Features
Because the A22TK Safety Key Selector Switch uses the same key as the Guard Lock Safety-door Switch, the operator is prevented from forgetting
to remove the key. The result is a safer working environment when performing maintenance.

Safety can

ensured,
but
there is a risk of human error

Guard Lock Safety-door Switch
Guard Lock Safety-door Switch
only
When only the Door Switch is
used,
the operator is at risk of
being
shut inside the
barrier
if, for example, he/she forgets to remove the
trapped key and a third party locks the door.
The equipment may also
be
star ted
up while
the operator is inside.
+
Key Selector Switch (A22K)
The safety level is enhanced
by
switching to maintenance mode.
However,
because
two different types of keys are required,
the operator is still at risk of
being
shut inside if he/she forgets to
remove the trapped key.

By
using
a common key, the risk of human error is reduced in operations
from
when
the door is open/shut
until
the equipment is started.
Guard Lock Safety-door Switch
+
Safety Key Selector Switch (A22TK)
The two locks on the door and equipment
use
the same key, reducing the likelihood that the
user will
forget to remove it.
In addition, the key cannot
be
removed
when
maintenance is
being
performed. This prevents the key from
being
lost and greatly
reduces the risk of an operator
becoming
trapped inside.
