Imagine being in a control room filled with buttons, lights, and levers, each representing a key part of a complex system. Without clear signage, understanding what each command does would be a near-impossible task.
Therefore, in electrical control panels, signage is key to transforming this complexity into something accessible and safe. It serves as a visual language that communicates functions, alerts, and operating status.
This allows technicians and operators to 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 types of buttons are there?
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 for precise controls, contributing to the system's safety and efficiency. The choice of pushbutton panel type depends on specific operating needs and the desired level of security.
Learn about the main types of buttons.
Detent button (or toggle switch)
It has fixed positions, such as on/off. It's practical because it combines functions in a single button, but it can pose risks in the event of a power outage. After all, it maintains its position and can automatically reactivate the circuit when power is restored.
Non-retaining button (or push button)
Operates only when pressed, making it ideal for temporary operation. Requires a seal contact to keep the circuit activated.
This way, it is safe in case of a power outage, as the circuit turns off automatically, but it takes up more space because it needs separate buttons to turn it on and off.
Combined button (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 non-latching pushbutton, requiring a sealing contact to keep the circuit on.
Mushroom (or emergency) button
Designed for emergency situations, it shuts off the circuit when pressed. It has a locking mechanism, requiring a specific action, such as turning the knob, to unlock.
It generally uses NC (Normally Closed) contacts to disconnect and NO (Normally Open) to signal emergency.
What do the colors of the traffic lights mean?
Light signaling on electrical panels ensures that operators quickly understand the status of machines and processes.
Thus, standardized colors allow you to identify operating conditions, failures or alert situations intuitively and efficiently, promoting safety and agility in decision-making.
See the meanings of each color:
- Green: indicates that the machine or system is ready to operate. It represents optimal, fault-free operation. It's a sign that everything is under control;
- Red: Indicates a warning or danger. Used when the machine is stopped due to an overload, critical failure, or activation of protective devices. Therefore, it is a call for immediate attention to avoid risks;
- Yellow: Represents attention or caution. It usually indicates system failures, but without imminent risk. Therefore, it signals the need for verification before proceeding;
- White (or colorless): indicates normal operation. It is used to show that the machine is working or moving, but without the need for intervention;
- Blue: used to signal specific functions not covered by other colors — such as auxiliary commands or customized operating conditions.
