Button NEF30-KX blue W0-NEF30-K X N

Universal control button NEF30

The NEF30 control button is a reliable and robust solution for controlling devices in various industrial and automation applications. Designed for mounting in 30.5 mm diameter holes, it is ideal for control panels, distribution boards and machine housings. The construction based on a metal body provides high mechanical resistance and durability, and climatic versions N/2 and W/3 allow adaptation to specific environmental conditions.

Construction and application

This button, in blue color, is of the momentary type – it automatically returns to the initial position after being pressed. It has one normally open (NO) and one normally closed (NC) contact, which allows flexible use in control circuits. The ability to configure with various switching elements (e.g. 2X2Y) allows adaptation to individual project needs. Thanks to the protection class IP55 (and IP56 in some versions), the button is resistant to dust and water ingress, guaranteeing reliable operation even in harsh conditions.

Key features and benefits

• Durable construction: Metal body ensures long-term operation and resistance to mechanical damage.
