Why Choose the Pizzato E21PU1F249L2 Maintained Mushroom Pushbutton?
The Pizzato E21PU1F249L2 is a robust maintained mushroom 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 in a compact, panel-mounted format.
This actuator features a white Ø 36 mm mushroom button with an “I” marking for clear function identification. Its maintained action keeps the button in its operated position after it is pressed and requires a second manual operation to release it, making it suitable for control functions where a retained command is required.
With IP67 and IP69K protection, the E21PU1F249L2 is engineered for industrial environments exposed to dust, water and high-pressure cleaning. Its satin-chrome bezel provides a durable, professional panel finish, while the modular E2 design enables compatible Pizzato contact blocks to be selected for the required switching circuit.

Dependable Maintained Control for Industrial Machinery
A maintained pushbutton remains mechanically engaged after operation and must be manually released to return to its initial position. This behaviour is useful for machine functions that require a persistent command rather than a momentary electrical impulse.
The large mushroom profile provides a broad operating surface, while the “I” marking helps identify the assigned control function. Compatible Pizzato E2 contact blocks can be fitted to create the normally open or normally closed contact arrangement required by the machine circuit.
Typical Applications
- Industrial machinery control panels.
- Operator stations and control consoles.
- Manufacturing and assembly equipment.
- Conveyor and material-handling systems.
- Packaging and processing machinery.
- Washdown and high-cleanliness production environments.
