Why Choose the Pizzato FC3393-F3M2 Safety Interlock Switch?
The Pizzato FC3393-F3M2 is a high-reliability 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 machinery can only operate when protective doors or safety guards are correctly closed and secured.
Built for demanding industrial environments, the FC3393-F3M2 features a robust metal housing and a high IP67 protection rating, offering excellent resistance against dust, moisture, and vibration. It is widely used in automated machinery, production lines, and safety enclosures where reliable guard position monitoring is essential for operator protection.
This version uses a separate actuator (F3M2 configuration), where the switch body is mounted on the fixed frame and the actuator is installed on the moving guard. When the guard is opened, the actuator is withdrawn, immediately changing the safety contact state and preventing hazardous machine operation.

Reliable Machine Guard Protection
The FC3393-F3M2 works using a separate actuator mounted on the moving guard. When the guard is closed, the actuator engages the switch, allowing machine operation. When the guard is opened, the actuator is withdrawn from the sensing head, immediately triggering a safety response and stopping or preventing restart.
This ensures operators are protected from hazardous machine movement during maintenance, inspection, or access events.
Typical Applications
- Machine guarding systems.
- Safety doors and access panels.
- Industrial automation equipment.
- Robotic cells and safety fences.
- Packaging and processing machinery.
- OEM machine safety systems.
