In our daily lives, we can see that each light switch has an on and off symbol written on it. However, there are still many friends who are not clear about what on and off represent respectively. Some people also wonder why on and off are used to represent switches. Today, let's talk about it and take a look together.



On and off are expressions in English and international terms, with sentence patterns of "turn on" and "turn off". On and off represent the switch status of the power supply. Due to their short and international vocabulary, they are used in many places and greatly save on the manufacturing cost of the switch. If Chinese characters are used to represent the switch status, it is not conducive to international production and will increase the use of resources.
