Can I use the light switch on the telephone line?

Telephone lines don't need 3C.

Generally, 3C products are electrical products, and these products are sold in China!

Electrical products are generally greater than 36V, that is, higher than the human safe voltage, which requires 3C!

If you still don't understand anything, you can call directly and ask if you want to do 3C!

Generally speaking, 3C needs to be completed as follows:
