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

@

D4SL-NSK10-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)

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.

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.

For the most recent information on models that have been certified for 
safety standards, refer to your OMRON website.

Broad range of applications include use with door locks, mode switching, and emergency stops when teaching 

Common Key for Door Switch and Selector Switch

With the Selector Switch, it is possible to 
switch between normal operation mode 
(use of Door Switch is available) and 
maintenance mode (use of Enabling 
Grip Switch is available).
