Why Choose the Pizzato FD 541-K21 Position Switch?
The Pizzato FD 541-K21 is a heavy-duty position switch with bi-stable operation, designed for reliable mechanical detection and maintained switching in industrial automation systems. As part of the durable Pizzato FD series, it delivers consistent switching performance and long operational life in demanding environments.
This K21 variant features a metal housing with PG 13.5 threaded conduit entry and an integrated cable gland for 6–12 mm cable diameters, simplifying installation and ensuring secure cable entry. It includes a 1NO + 1NC snap action contact block with bistable switching, allowing the switch to maintain its position after actuation.
With an IP67 protection rating and positive opening, the FD 541-K21 is designed to operate reliably in harsh industrial environments exposed to dust, moisture and vibration, making it suitable for both control and safety-related applications.

Bistable Switching for Controlled Machine States
The FD 541-K21 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.
Its snap action contacts ensure fast switching response, while the integrated cable gland reduces installation time and improves sealing performance in industrial environments.
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.
