Meaning of the well-known power symbol
The famous energy symbol, which consists of a circle with a vertical line inside, is one of the most universal symbols in electronic device technology. It appears on phones, computers, and household appliances. It first appeared in the 1950s, when mechanical switches were more common, and was designed so that everyone could understand it without translation, due to its use of the binary code system (1 and 0) that signifies on and off. As devices evolved, the function of the power button shifted from completely turning off the device to standby mode, but the symbol remained a simple and unified representation of controlling the power on and off.
