A22LK

Selector Switch for secure equipment activation during maintenance

The guard lock of the Operation Unit prevents incorrect operation.

The key has the same shape as the following keys.
 • The key of the A22TK Safety Key Selector Switch
 • The trapped key of the D4JL Guard Lock Safety-door Switch
 • The lockout key of the D4SL-NSK10-LK Slide Key Unit

Because the A22LK Guard Lock 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.
