Why Choose the Pizzato FC3393-M2 Safety Interlock Switch?
The Pizzato FC3393-M2 is a reliable key-operated safety interlock switch designed for machine guarding, access control, and industrial safety applications. As part of the Pizzato FC series, it ensures machinery can only operate when protective doors, covers, or safety guards are correctly closed and secured.
Built for demanding industrial environments, the FC3393-M2 features a robust metal housing and a high IP67 protection rating, providing excellent resistance against dust, water ingress, and vibration. It is widely used in automation systems, production machinery, and safety enclosures where dependable guard position monitoring is required.
This model uses a key-operated interlocking mechanism, where an actuator/key is inserted into the switch to enable machine operation. When the key is removed or the guard is opened, the safety contacts immediately change state, triggering a machine stop or preventing restart to protect operators.

Reliable Machine Guard Protection
The FC3393-M2 works by controlling machine enable/disable status through a keyed safety mechanism. When the guard is closed and the key is correctly engaged, the machine is allowed to operate. When the key is removed or the guard is opened, the internal safety contacts switch state and immediately trigger a safe stop condition.
This ensures that hazardous machine movement cannot occur during access, maintenance, or inspection, significantly improving operator safety in industrial environments.
Typical Applications
- Machine guarding systems.
- Safety doors and access panels.
- Industrial automation equipment.
- Robotic work cells and fenced areas.
- Packaging and processing machinery.
- OEM machine safety systems.
