Push-button panel DeLOCK 20978 Silver 230V 3A

The DeLOCK 20978 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 equipment that require a reliable push-button switch. The device operates at an input voltage of 230 V and supports a maximum switching current of 3 A. Its small footprint (30 mm wide, 25 mm deep) makes it suitable for space-constrained applications in industry, regulation technology, automotive and certain consumer installations such as doorbells or timed lighting controls.

Advantages

The push-button features a robust metal construction (nickel and stainless steel) that offers mechanical durability and a neutral silver appearance. It is a momentary push button that returns to its initial position after being pressed, and provides both NO (normally open) and NC (normally closed) contact behaviors for flexible wiring and control logic. Rated for 230 V and up to 3 A, it is suitable for many low-power control circuits.

Suitable for

• Control panels in industrial and regulation systems
• Automotive control interfaces requiring momentary switches
• Consumer applications such as doorbells
• Timed lighting systems and hallway lighting triggers

How to use

Mount the push button into a suitably sized panel cutout and secure it according to the panel mounting requirements. Wire the contacts according to the desired function: use the NO contact for circuits that should close only when the button is pressed, or the NC contact for circuits that should open when the button is pressed. Ensure the supply is 230 V and that connected loads do not exceed the 3 A rating. Perform standard electrical safety checks before commissioning.

Recommendations

Use the DeLOCK 20978 push button in low-power control circuits and cabinets where a durable metal momentary switch is required; avoid exceeding the 3 A rating and protect the circuit with appropriate fusing or circuit breakers.
