What does the M1 refer to in the context of electrical systems?

In the context of electrical systems, M1 typically refers to a Voltage Selector Switch. This component is critical because it allows users to adjust the voltage level that is supplied to a device according to the requirements of the system or the input from different power sources. It helps ensure that the electrical equipment operates within its specified voltage range, protecting it from potential damage caused by overvoltage or undervoltage scenarios.

The awareness of voltage settings is essential for optimal performance and safety in various electrical applications. Understanding the function and importance of the Voltage Selector Switch is fundamental for those in the field, particularly for Fire Controlmen, as it directly relates to the safe operation of electronic systems and equipment.
