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.
