## Summary description

The Promet W0-NEF30-UD XY C is a 30mm industrial push button switch featuring a red actuator and a momentary contact configuration with 1 normally open (NO) and 1 normally closed (NC) contact. Designed for reliable control in automation and electrical panels, this robust switch ensures precise operation and durability in demanding industrial environments.

## Long description

The Promet W0-NEF30-UD XY C is a high-quality 30mm industrial push button switch engineered for reliable control in demanding electrical environments. Featuring a distinct red actuator, this momentary switch provides clear visual identification and tactile feedback. It is equipped with one normally open (NO) and one normally closed (NC) contact, making it a versatile component for various automation and control panel applications where precise switching is required.
Advantages
This push button switch is built for durability and consistent performance in industrial settings. Its robust construction ensures long-term reliability even under frequent use. The momentary contact configuration allows for precise control signals, while the standard 30mm mounting diameter ensures compatibility with a wide range of existing control panels and machinery interfaces. The inclusion of both NO and NC contacts provides flexibility in circuit design, allowing for both normally energized and normally de-energized control logic.
Suitable for
Industrial control panels
Automation systems
Emergency stop or signal initiation
Machinery control interfaces
Electrical distribution boards
When it may not be suitable
This switch is not intended for high-power direct switching of heavy loads without a contactor or relay. It is designed for control circuits rather than power distribution. Additionally, it is not suitable for applications requiring a maintained or latching action, as the momentary mechanism will return to its default state immediately upon release.
Key specifications
Mounting diameter: 30mm
Actuator color: Red
Contact configuration: 1NO (Normally Open) + 1NC (Normally Closed)
Operation type: Momentary
Application: Industrial control
How to use
Installation involves mounting the switch into a standard 30mm hole on a control panel or enclosure. Ensure the locking nut is tightened securely to prevent rotation during operation. Connect the control wires to the appropriate terminals on the contact block, ensuring that the NO and NC terminals are wired according to your specific circuit requirements. Once installed, the switch is operated by pressing the red actuator, which triggers the contact state change; releasing the button returns it to its original position.
What to consider before purchase
Verify the mounting hole diameter of your panel is 30mm.
Ensure the momentary action is appropriate for your specific control logic.
Check that the 1NO+1NC contact arrangement meets your circuit requirements.
Confirm the environmental conditions are compatible with the switch specifications.
Usage recommendations
For optimal longevity and safety, ensure that the electrical load connected to the switch contacts does not exceed the rated current and voltage limits. Regularly inspect the switch for any signs of mechanical wear or debris accumulation that could impede the actuator movement.
