Why Choose the Pizzato FD 542 Position Switch?
The Pizzato FD 542 is a heavy-duty position switch with bi-stable double-track lever, designed for reliable mechanical detection and maintained switching in industrial automation systems. As part of the robust Pizzato FD series, it delivers consistent 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 (B5). It incorporates a bistable double-track lever actuator, allowing the switch to maintain its position after actuation, making it ideal for applications requiring stable switching states.
With an IP67 protection rating and positive opening, the FD 542 is engineered to operate reliably in harsh industrial environments exposed to dust, moisture and mechanical stress.
Key Advantages
- Bistable operation for maintained switching states.
- Double-track lever actuator for enhanced mechanical control.
- 1NO + 1NC contact configuration for flexible control circuits.
- Snap action switching for fast and precise response.
- Positive opening ensures reliable safety circuit disconnection.
- IP67 protection rating for resistance to dust and water ingress.
Key Features
- Pizzato FD series heavy application position switch.
- FD 542 with bi-stable double-track lever actuator.
- Metal housing with industrial-grade construction.
- PG 13.5 cable entry.
- 1 normally open + 1 normally closed contact.
- Snap action switching mechanism (B5).
- Silver contact material.
- Two stable positions (bistable switching).
- IP67 protection rating according to EN 60529.
Bistable Switching for Controlled Machine States
The FD 542 maintains its switching position after actuation, making it ideal for applications where a machine state must be retained without continuous input. This bistable function simplifies control logic and improves operational stability in automated systems.
The double-track lever actuator provides enhanced actuation reliability and improved detection accuracy for moving machine parts, especially in applications requiring consistent mechanical engagement.
Typical Applications
- Machine control systems requiring maintained switching states.
- Industrial automation and control panels.
- Position monitoring of machinery and tooling.
- Conveyor and material handling systems.
- Packaging and production machinery.
- Safety and interlocking applications.

Frequently Asked Questions
What is the Pizzato FD 542 used for?
The FD 542 is used for detecting position and maintaining a switched state in industrial machinery due to its bistable operation.
What is a double-track lever?
A double-track lever provides two-point mechanical contact, improving reliability and stability when actuating the switch.
What does bistable operation mean?
It means the switch remains in its last actuated position until it is triggered again.
What contact configuration does the FD 542 have?
The switch features a 1NO + 1NC snap action contact block, suitable for control and signalling applications.
Is the FD 542 suitable for harsh environments?
Yes. With an IP67 rating, it is protected against dust and water ingress.
