  • Safety Mechanism: The key remains trapped while the switch is in the "ON" (closed) position, only released when the switch is moved to the "OFF" (open/isolated) position.
  • Applications: Ideal for high-voltage (HV) substations, ring main units (RMU), and, in Siemens kits, MCCBs (e.g., 3VT, 3VA).
  • Types: Models include FS, Q, and specialized interlocks for panel doors and access.
  • Operation: A 
     square 
     
     spigot (or similar) is typically used for mechanical connection to the switch.
  • Benefits: Ensures safety by enforcing a strict sequence, protecting against human error during maintenance, and suitable for harsh environments
