Why Choose the Pizzato FC3493-F1 Safety Interlock Switch?
The Pizzato FC3493-F1 is a high-reliability 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 guards, doors, or access panels are securely closed and correctly positioned.
Built for harsh industrial environments, the FC3493-F1 features a rugged metal housing and a high IP67 protection rating, providing resistance against dust, moisture, and vibration. It is widely used in automated machinery, production lines, and safety enclosures where dependable guard position monitoring is required to protect operators and equipment.
This model is the F1 actuator configuration variant, designed for specific guard alignment setups where a compact key-operated interlock is required. When the key/actuator is engaged, machine operation is enabled; when it is removed or the guard is opened, the safety contacts immediately switch state to stop hazardous motion.
Key Advantages
- Reliable key-operated safety interlock system for machine guarding.
- Prevents machine operation when guards are open or not secured.

Reliable Machine Guard Protection
The FC3493-F1 operates using a key-based safety interlock mechanism installed on machine guards or access doors. When the guard is closed and the key is engaged, the machine is enabled. When the guard is opened or the key is removed, both safety contacts open, immediately triggering a safe stop condition.
This ensures that hazardous machine movement cannot occur during access, maintenance, or inspection, improving operator safety and compliance with industrial machine safety standards such as EN ISO 14119.
Typical Applications
- Machine guarding systems.
- Safety doors and access panels.
- Industrial automation equipment.
- Robotic cells and fenced areas.
- Packaging and processing machinery.
- OEM safety-rated machine systems.
