## Long description

The Promet W0-NEF30-K XY N is a high-quality 30mm diameter momentary push button switch designed for industrial control applications. Featuring a distinct blue actuator, this switch is engineered for reliability and durability in demanding environments. It is equipped with a 1NO (normally open) and 1NC (normally closed) contact configuration, providing versatile switching options for various electrical control circuits.
Advantages
This push button switch offers exceptional mechanical durability, ensuring consistent performance even in high-frequency usage scenarios. The momentary action mechanism provides precise control, as the circuit remains active only while the button is physically depressed, which is essential for safety-critical operations. Its standard 30mm mounting diameter allows for easy integration into existing control panels and machinery consoles, while the clear blue color helps operators quickly identify specific control functions within complex systems.
Suitable for
Industrial control panels
Automation and robotics systems
Manual start, stop, and reset functions
Electrical machinery operation
When it may not be suitable
This switch is not intended for applications requiring a latched or maintained state, where the button must remain pressed after release. It is also not suitable for high-power direct load switching without appropriate contactors or relays, as it is designed primarily for control signal circuits.
Key specifications
Mounting diameter: 30mm
Contact configuration: 1NO (normally open) and 1NC (normally closed)
Operation type: Momentary
Color: Blue
How to use
Installation should be performed by qualified personnel in accordance with electrical safety standards. The switch is mounted into a 30mm hole on a control panel or enclosure. Once secured, the electrical wires are connected to the 1NO and 1NC terminals located on the rear of the unit. Ensure that the wiring matches the requirements of your control circuit. Once installed, the switch is operated by manually pressing the blue button to trigger the momentary contact change.
What to consider before purchase
Verify the mounting hole diameter of your panel matches the 30mm requirement.
Ensure the 1NO/1NC contact configuration meets your specific circuit logic needs.
Confirm that a momentary action is appropriate for your intended control task.
Usage recommendations
Regularly inspect the switch for physical damage and ensure that the electrical connections remain tight to prevent signal loss or intermittent operation in industrial environments.
