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.
Common Key for Door Switch and Selector Switch
Broad range of applications include use with door locks, mode switching, and emergency stops when teaching

Safety can be ensured, but there is a risk of human error
occurring during operation.

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 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.
The equipment may also be started up while the operator is inside.

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.

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.

such as pointed-nose pliers. Doing so will damage the mounting
ring. The tightening torque is 0.98 to 1.96 N·m.
• Do not use the switch submerged in oil or water or in locations
continuously subject to splashes of oil or water. Doing so may
result in oil or water entering the switch.
• Recommended panel thickness: 1 to 5 mm.
Wiring
Mounting the Lock Plate
• Connect a fuse in series with the A22TK to protect it from
shortcircuit damage. The value of the breaking current of the fuse
must be calculated by multiplying the rated current by 150ꢀ to
200ꢀ.
1. Confirm that the lever on the Mounting Latch is on the side where
the Operation Unit is secured and then insert the protrusion on the
Lock Plate into the hole in the lever on the Mounting Latch.
2. Press the hole on the Lock Plate onto the protrusion on the Mount-
ing Latch until it clicks into place.
When using the A22TK for an EN rating, use a 10-A fuse of type gI
or gG that complies with IEC 60269.
After mounting the Lock Plate, check that the lever does not move.
• Always make sure that the power is turned OFF before wiring the
Switch.
Also, do not touch the terminals or other current-carrying ports
while power is being supplied.
