## Long description

The Promet W0-NEF30-W XY C is a high-quality 30mm red momentary push button engineered for industrial control panels and automation systems. This device features a reliable spring-return mechanism, ensuring the button returns to its original position immediately after release. It is equipped with one normally open (1NO) and one normally closed (1NC) contact block, providing versatile switching capabilities for various electrical control circuits.
Advantages
This push button is built to withstand the rigors of industrial environments, offering high durability and consistent performance. The 30mm mounting diameter is a standard size, allowing for easy integration into existing control panels or new machine designs. The inclusion of both 1NO and 1NC contacts provides flexibility in circuit configuration, enabling both signal activation and safety interlock functions within a single compact unit.
Suitable for
Industrial machine control panels

Electrical equipment monitoring
When it may not be suitable
This momentary push button is not intended for applications requiring a maintained or latching state, where the button must stay pressed after activation. It is also not suitable for high-power direct switching of heavy loads without the use of intermediate relays or contactors.
Key specifications
Mounting diameter: 30mm
Button color: Red
Operation type: Momentary (spring-return)
Contact configuration: 1NO (Normally Open) and 1NC (Normally Closed)
How to use
To install the push button, insert the actuator through a 30mm hole in the control panel and secure it using the provided locking nut. Connect the electrical wires to the 1NO and 1NC contact blocks according to your circuit diagram. Once installed, pressing the red button will change the state of the contacts, and releasing it will cause the spring mechanism to return the button to its default state.
What to consider before purchase
Verify that the 30mm mounting hole size matches your panel requirements.
Ensure the 1NO and 1NC contact configuration meets your specific control logic needs.
Confirm that the momentary operation is appropriate for your intended application.
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring or maintenance on the control panel to prevent electrical hazards.
