Why Choose the Pizzato FD 540 Position Switch?
The Pizzato FD 540 is a heavy-duty position switch with two stable positions, designed for reliable mechanical detection in industrial automation and control systems. As part of the robust Pizzato FD series, it delivers dependable switching performance and long service life in demanding industrial environments.
This model features a metal housing with PG 13.5 threaded conduit entry and a 1NO + 1NC snap action contact block. Its bistable (two stable position) operation allows it to maintain its switching state after actuation, making it ideal for applications requiring maintained switching rather than momentary contact.
With an IP67 protection rating and durable construction, the FD 540 is designed to perform reliably in environments exposed to dust, moisture and mechanical stress, while ensuring consistent operation in industrial control systems.
Key Advantages
- Bistable (two stable position) operation for maintained switching.
- 1NO + 1NC contact configuration for flexible control circuits.
- Snap action switching for fast and precise response.
- IP67 protection rating for resistance to dust and water ingress.
- Metal enclosure for long-term industrial durability.
- Reliable performance in demanding automation environments.
Key Features
- Pizzato FD series heavy application position switch.
- FD 540 bistable position switch.
- Metal housing with industrial-grade construction.
- PG 13.5 cable entry.
- 1 normally open + 1 normally closed contact.
- Snap action switching mechanism.
- Silver contact material.
- Two stable positions (maintained switching).
- IP67 protection rating according to EN 60529.
Bistable Switching for Controlled Machine States
Unlike standard momentary switches, the FD 540 maintains its switching position after actuation. This bistable operation is particularly useful in applications where a machine state must be retained without continuous force or input.
The snap action mechanism ensures rapid switching, while the robust FD series design provides durability and consistent performance even in high-use industrial environments.
Typical Applications
- Machine control systems requiring maintained switching states.
- Industrial automation and control panels.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Position control with bistable switching requirements.
- Heavy-duty industrial installations.

Frequently Asked Questions
What is the Pizzato FD 540 used for?
The FD 540 is used for detecting position and maintaining a switched state in industrial machinery due to its bistable design.
What does “two stable positions” mean?
It means the switch remains in its last actuated position until it is triggered again, rather than returning automatically.
What contact configuration does the FD 540 have?
The switch features a 1NO + 1NC snap action contact block, suitable for control applications.
Is the FD 540 suitable for harsh environments?
Yes. With an IP67 rating, it is protected against dust and water ingress.
Does the FD 540 include an actuator?
No. The unit is supplied without an actuator, allowing selection of compatible rotating lever accessories.
