Professional Custom Lamp Holder Accessories Manufacturer

Lamp holders: Fire, zero two lines.

Fire into the switch, come out to accept the lamp; the zero directly connected lamp holders.
Note: If the lamp holder is a kind of spiral, remember to pick out of the line of fire from the switch to the the Lamp middle that interface, and zero cord to the lamp holders shell interface, so even if forget to turn off the switch when changing a light bulb, also does not result in an electric shock!
