The function of button switch, originally so important

With the progress of society, electricity has become an indispensable source of energy for every household. It is indispensable for daily life, such as washing, cooking and watching TV. I still remember when I was young, there was often power cut in the countryside. At that time, I didn't feel anything. But now if there is no electricity, I can't imagine what our life will be like. Electricity has brought a lot of convenience to our life, but at the same time there are a lot of security risks. In each of our homes there is a button switch, critical time can save lives, must be pressed once a month, unfortunately many people ignore. Today, I will tell you about the function of this "button switch". Let's learn about it with me.

There is a "button switch" at home to save lives, must be pressed once a month, learn to enjoy life!

I believe that everyone has a such a distribution box at home, the home of all kinds of circuit switches are installed in it, the distribution box inside in addition to the line, there is a very important switch, the key time can save lives. The switch is the leakage circuit breaker, its main role is in the home of equipment leakage fault, with overload and short circuit protection function, leakage accident in the home, can play a very key role, so the leakage circuit breaker is every household must install.

This leakage circuit breaker has a "button switch" above, you can take a closer look at this place in the home, it clearly says "press once a month." You must be very confused, why do you have to press once a month? This is because this small button is actually to check whether the leakage circuit breaker is out of order. If we press this button, the leakage circuit breaker can trip normally, indicating that the leakage circuit breaker is intact. If you can not trip, it is likely that the leakage circuit breaker is out of order. When there is leakage or short circuit in the home, you can not automatically power off normally. It is found that this situation, we will be better leakage circuit breaker for the first time, in order to ensure the safety of electricity in the home.
