FP 7R2 Pizzato Safety switch with manual mechanical delay
Pizzato FP 7R2 is an IP67 technopolymer safety interlock switch with separate-actuator operation, 1NO + 1NC slow-action make-before-break contacts and an approximately 20 second manual mechanical guard-release delay.

Why Choose the Pizzato FP 7R2 Safety Switch?
The Pizzato FP 7R2 is a safety switch with separate actuator and manual mechanical delay designed for machine guarding applications where access should remain restricted for a short period after a stop command. Part of the Pizzato FP series, it combines guard interlocking with a purely mechanical delayed-release mechanism for machinery where hazardous movement may continue after power is removed.
In its standard configuration, the FP 7R2 uses a short release knob with an approximately 20 s mechanical delay. Its 1NO + 1NC slow-action contact block provides make-before-break operation, while positive-opening operation ensures direct mechanical opening of the relevant safety contact.
The FP 7R2 features a durable technopolymer housing, IP67 protection and one threaded conduit entry. The standard FP 7R2 configuration does not specify an actuator, allowing a compatible Pizzato separate actuator to be selected according to the guard geometry and installation requirements.
Key Advantages
- Combines machine guard interlocking with manual mechanical delayed release.
- Standard configuration provides an approximately 20 s delay for machinery with residual movement.
- 1NO + 1NC slow-action contacts provide safety and auxiliary switching functions.
- Make-before-break contact operation for the FP 7R2 contact configuration.
- Positive-opening operation provides direct mechanical opening of the relevant safety contact.
- Compatible actuator can be selected separately to suit the guard arrangement.
- IP67 technopolymer enclosure supports demanding industrial installations.

Mechanical Delayed Guard Release for Machinery with Residual Motion
Manual mechanical delay safety switches are intended for machines where rotating or other hazardous components may continue moving after a stop command. The standard FP 7R2 mechanically retains the separate actuator for approximately 20 s, providing additional time for residual movement to reduce before the protective guard can be opened.
Because the timing function is mechanical, no electrically powered solenoid is required to generate the release delay. This makes the FP 7R2 a practical guard-interlocking solution for appropriate machinery with predictable rundown times, subject to the requirements of the machine's overall risk assessment and safety system.
Typical Applications

- Saws and cutting machinery.
- Grinding and processing equipment.
- Flywheels, pulleys and high-inertia drive systems.
- Packaging and production machinery.

Frequently Asked Questions
What is the Pizzato FP 7R2 used for?
The Pizzato FP 7R2 is designed for machine guard interlocking where access should remain mechanically delayed after a stop command, particularly on suitable machinery with residual hazardous movement.
What is the standard delay time of the FP 7R2?
The standard FP 7R2 configuration uses a short release knob with an approximate 20 s manual mechanical delay.
What contact configuration does the FP 7R2 have?
The FP 7R2 provides 1NO + 1NC slow-action contacts with make-before-break switching operation.
Does the FP 7R2 provide positive-opening operation?
Yes. The switch provides positive-opening safety operation, ensuring direct mechanical opening of the relevant safety contact.
Is an actuator supplied with the standard FP 7R2 configuration?
No specific actuator is designated in the standard FP 7R2 part number, allowing a compatible Pizzato separate actuator to be selected according to the machine guard geometry and installation requirements.
What is the protection rating of the Pizzato FP 7R2?
The FP 7R2 provides IP67 protection according to EN 60529, supporting installation in industrial environments requiring protection against dust and water ingress.
Does the FP 7R2 require a solenoid to provide its delay?
No. The delayed-release timing is generated by a manual mechanical mechanism, so an electrically powered solenoid is not required to create the delay.
