Guard Lock Safety Key Selector Switch


The guard lock prevents accidental mode changes.

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.
