Signaling and colors in electrical control panels: the guide

Therefore, in electrical control panels, signaling is the key to transforming this complexity into something accessible and safe. It serves as a visual language that communicates functions, alerts, and operational status.

Thus, technicians and operators can act with precision, avoiding errors and ensuring efficiency. This visual organization is essential for the safety and reliability of the entire system. After all, when every detail matters, clarity makes all the difference, don't you agree?

What are the existing types of pushbuttons?

Pushbuttons are control devices used to operate, command, or interrupt electrical circuits in machines and equipment. They are widely used in control panels, providing a direct and intuitive interface for operators.

They generally have a robust structure and allow precise commands, contributing to the safety and efficiency of the system. The choice of pushbutton type depends on the specific operation needs and the desired level of safety.

Maintained pushbutton (or selector switch)

It has fixed positions, such as on/off. Thus, it is practical for combining functions in a single button, but it can pose risks in cases of power failure. After all, it maintains its position and can automatically reactivate the circuit upon power restoration.

Momentary pushbutton (or pulse button)

It acts only while pressed, making it ideal for temporary operations. It requires a seal-in contact to keep the circuit activated.

This way, it is safe in case of a power failure, as the circuit turns off automatically, but it takes up more space because it needs separate buttons to turn on and off.

Dual pushbutton (on/off)

It combines the on and off functions in a single button, usually with color divisions (green for on and red for off). It works as a momentary pushbutton, requiring a seal-in contact to keep the circuit on.

Mushroom pushbutton (or emergency stop)

Designed for emergency situations, it turns off the circuit when pressed. It features a maintained action, requiring a specific action, such as twisting the button, to release.

It generally uses NC (Normally Closed) contacts to turn off and NO (Normally Open) to signal an emergency.

What do the colors of the indicator lights mean?

Luminous signaling in electrical panels ensures that operators quickly understand the status of machines and processes.

Thus, standardized colors allow identifying operating conditions, faults, or alert situations intuitively and efficiently, promoting safety and agility in decision-making.
