## Long description

The Promet W0-NEF30-K 2X N is a high-quality 30mm diameter momentary control pushbutton designed for industrial automation and electrical control systems. Featuring a distinct blue actuator, this switch is engineered for durability and reliable performance in demanding environments. It is equipped with two normally open (2NO) contacts, providing a robust solution for various switching applications where a temporary signal is required.
Advantages
This control pushbutton offers exceptional reliability due to its robust construction and high-quality materials. The momentary action mechanism ensures that the switch automatically returns to its initial position after being released, which prevents accidental continuous activation. Its standard 30mm mounting diameter makes it highly compatible with most industrial control panels and enclosures, simplifying the installation process for technicians and engineers.
Suitable for
Start and stop functions in machinery
Resetting alarm or control systems
Manual signal triggering in automation processes
Electrical control panel integration
This switch may not be suitable for applications requiring a maintained or latching state, as the contact returns to its open position immediately upon release. It is also not intended for use in environments with extreme chemical exposure or high-pressure washdown conditions unless housed in an appropriately rated protective enclosure.

To use the Promet W0-NEF30-K 2X N, mount the unit into a standard 30mm hole on your control panel or enclosure. Secure the locking nut firmly to ensure the switch remains stable during operation.

Once installed, the button can be pressed to complete the circuit, and it will automatically disconnect when released.
What to consider before purchase
Verify that your control circuit requires a 2NO contact configuration.
Ensure the 30mm mounting hole size matches your panel specifications.
