Why Choose the Pizzato E21PU1R121L1 Maintained Flush Pushbutton?
The Pizzato E21PU1R121L1 is a compact and robust maintained flush 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 with a low-profile panel interface.
This actuator features a black Ø 20 mm flush button with an “O” 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 stop and control functions where a retained command is required.
With IP67 and IP69K protection, the E21PU1R121L1 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.

Low-Profile 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 flush profile creates a streamlined control-panel surface and helps reduce unintended operation on busy machinery interfaces.
The black actuator and “O” marking provide clear identification of the assigned control function. Compatible Pizzato E2 contact blocks can be fitted to provide the normally open or normally closed contact arrangement required by the machine circuit.
Typical Applications
- Industrial machinery control panels.
- Operator stations and control consoles.
- Machine stop and retained control functions.
- Conveyor and material-handling systems.
- Packaging and processing machinery.
- Washdown and high-cleanliness production environments.
