Push-button panel DeLOCK 20979 Silver 230V 3A

The DeLOCK 20979 push-button panel is a compact control element with a silver finish made of nickel and stainless steel. It is designed for installation in control panels and other systems where a small, robust push button is required. The switch is rated for 230 V and up to 3 A and measures approximately 30 mm in width and 25 mm in depth.

Advantages

The stainless steel and nickel construction provides mechanical durability and a corrosion-resistant surface suitable for industrial and consumer environments. Its compact dimensions allow easy integration into control cabinets, wall panels or housings with limited space. The device includes both NO (normally open, closer) and NC (normally closed, opener) contact functions, enabling flexible wiring for different control tasks.

Suitable for

• Industrial control panels and regulation systems
• Automotive applications requiring a momentary push button
• Consumer installations such as doorbells or corridor lighting triggers
• Small housings or machines with limited panel space
