£19.46
The Pizzato FR33C1 is a heavy-duty industrial safety switch with slotted-hole lever actuation designed for monitoring hinged guards, machine doors, and protective access panels in automation and industrial machinery systems. Manufactured by Pizzato Elettrica, it ensures reliable safety signalling when a guard is opened, triggering immediate machine shutdown to protect operators and equipment.
As part of the robust FR series safety switch family, the FR33C1 is engineered for demanding industrial environments requiring high mechanical durability, precise switching performance, and strong resistance to dust, water, and mechanical stress. It is widely used in OEM machinery, conveyors, packaging equipment, and automated production lines.
The FR33C1 belongs to the “33” contact configuration group, designed for enhanced safety redundancy with multiple normally closed safety channels suitable for safety-critical machine interlock circuits. {index=1}
The Pizzato FR33C1 ensures safe machine operation by detecting guard or lever movement and immediately triggering safety circuits. This prevents unintended machine start-up and protects operators during maintenance, setup, and access operations.
Based on distributor and manufacturer information, the FR33C1 is part of the FR slotted-lever safety switch range designed with IP67 protection, high mechanical endurance, and positive opening safety contacts. It is commonly used in machinery requiring multiple NC safety channels for redundant fail-safe operation in industrial environments.
