## Long description

The Promet W0-NEF30-K 2X Z is a high-quality 30mm green control pushbutton designed for industrial automation and electrical control systems. This momentary switch provides a reliable interface for manual signaling and command input, featuring two normally open (2NO) contacts that close only while the button is pressed. Its robust construction ensures durability in demanding environments, while the standard 30mm mounting diameter allows for easy integration into existing control panels and machinery consoles.
Advantages
This control pushbutton offers exceptional reliability and ease of use in industrial settings. The momentary action ensures that the signal is only active during the intentional press, preventing accidental continuous operation. With its two normally open contacts, it provides flexibility for complex control logic. The ergonomic design and clear green color allow for quick identification and comfortable operation by personnel, while the high-grade materials used in its construction guarantee a long service life even under frequent use.
Suitable for
Industrial control panels
Automation systems and machinery
Manual command input for electrical circuits
Signaling and process control applications
When it may not be suitable
This device is not intended for applications requiring a latching or maintained contact state, as it will return to its original position immediately upon release. It is also not suitable for high-power switching applications without the use of additional contactors or relays, as it is designed for control-level signals.
Key specifications
Mounting diameter: 30mm
Contact configuration: 2NO (two normally open)
Action type: Momentary
Color: Green
Application: Industrial control and signaling
How to use
Installation should be performed by qualified personnel in accordance with local electrical safety standards. The pushbutton is mounted into a 30mm hole on a control panel or enclosure and secured with the provided locking nut. Once mounted, the electrical wires are connected to the 2NO contact terminals. During operation, pressing the green button completes the circuit, and releasing it breaks the circuit, providing the momentary signal required for the connected control system.
What to consider before purchase
Ensure the 30mm mounting hole size is compatible with your panel design.
Verify that your control system requires a momentary signal rather than a latching one.
Confirm that the 2NO contact configuration meets the requirements of your specific electrical circuit.
Usage recommendations
Regularly inspect the pushbutton for physical damage and ensure that all electrical connections remain tight to prevent signal failure in critical automation processes.
