Why Choose the Pizzato FC3393-F1 Safety Interlock Switch?
The Pizzato FC3393-F1 is a compact key-operated safety interlock switch with separate actuator designed for machine guarding, access control, and industrial safety systems. As part of the Pizzato FC series, it ensures that machinery can only operate when protective doors, guards, or access panels are correctly closed and secured.
Engineered for demanding industrial environments, the FC3393-F1 features a rugged metal housing and a high IP67 protection rating, making it resistant to dust, moisture, and vibration. It is widely used in automation systems, production machinery, and safety enclosures where reliable guard position monitoring is essential for operator protection.
This version uses a separate actuator system, meaning the switch body is mounted on the fixed frame while the actuator (key) is mounted on the moving guard. When the guard is opened, the actuator is removed from the switch head, immediately changing the safety contact state and preventing machine operation.
Key Advantages
- Reliable safety interlock with separate actuator design.
- Prevents machine operation when guards or doors are open.

Reliable Machine Guard Interlocking
The FC3393-F1 operates using a separate actuator mounted on a movable guard. When the guard is closed, the actuator is inserted into the switch head, enabling machine operation. When the guard is opened, the actuator is withdrawn, immediately triggering a safety response.
This ensures hazardous machine motion cannot occur while access doors or protective enclosures are open, significantly improving operator safety during maintenance and operation.
Typical Applications
- Machine guarding systems.
- Safety doors and access panels.
- Industrial automation equipment.
- Robotic work cells and safety fences.
- Packaging and processing machinery.
- OEM machine safety systems.
