Why Choose the Pizzato FC3393-F Safety Interlock Switch?
The Pizzato FC3393-F is a compact and reliable key-operated safety interlock switch 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, covers, or safety guards are properly closed and secured.
Built for demanding industrial environments, the FC3393-F features a rugged metal housing and a high IP67 protection rating, offering excellent resistance to dust, water ingress, and vibration. It is widely used in automation equipment, production machinery, and safety enclosure systems where reliable guard position monitoring is essential for operator protection.
This version represents a variant of the FC3393 family with F-type actuator configuration, typically used in systems requiring flexible guard alignment and mechanical key engagement for safe machine operation. When the guard is opened or the actuator is disengaged, the safety contacts immediately switch state to stop hazardous motion.

Reliable Machine Guard Protection
The FC3393-F operates using a key-based interlocking mechanism installed on machine guards or access doors. When the guard is closed and properly engaged, machine operation is enabled. When the guard is opened or the key is removed/disengaged, the internal safety contacts change state and immediately trigger a safe stop condition.
This ensures that hazardous machine movement cannot occur during access, maintenance, or inspection, improving operator safety and compliance with industrial safety standards such as EN ISO 14119.
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.
