Why Choose the Pizzato E21PU1P421L2 Maintained Protected Pushbutton?
The Pizzato E21PU1P421L2 is a robust maintained protected pushbutton actuator designed for industrial machinery, operator stations and automation control panels. As part of the Pizzato E2 PU EROUND series, it provides dependable manual control while helping shield the button against unintended actuation.
This actuator features a green Ø 20 mm protected button with an “I” marking for clear function identification. Its maintained mechanism keeps the button in its operated position after it is pressed and requires a second manual operation to release it, making it suitable for start and control functions where a retained command is required.
With IP67 and IP69K protection, the E21PU1P421L2 is engineered for industrial environments exposed to dust, water and high-pressure cleaning. Its black bezel and plastic fixing ring support straightforward panel installation, while the modular E2 design enables compatible Pizzato contact blocks to be selected for the required switching circuit.

Protected Maintained Control for Industrial Machinery
A maintained pushbutton remains mechanically engaged after operation and must be manually released to return to its initial position. The protected profile surrounds the operating surface, helping reduce accidental actuation on busy machinery panels and operator stations.
The green actuator and “I” marking provide clear visual identification of the assigned command. Compatible Pizzato E2 contact blocks can be fitted to provide the normally open or normally closed contact arrangement required by the control circuit.
Typical Applications
- Industrial machinery control panels.
- Operator stations and control consoles.
- Machine start and retained control functions.
- Conveyor and material-handling systems.
- Packaging and processing machinery.
- Washdown and high-cleanliness production environments.
