Hi, I have another question, hope its not too confusing. You can also see that another live and neutral wire go to the next light switch. If taking the new light from the lighting circuit,which is the preffered option, there is no need for a fused spur/fcu.Just take a feed and neutral to the switch and then to the light.Makes it easier with one cable at the light. Can I disconnect the hot (black) wire and add a pigtail and feed power to my new switch? A three-way switch has an extra terminal because a pair of three-ways has to be connected to each other as well as to power and the light. I hooked the hot wire, neutral wire, and ground all from the 14/2 wire to the recessed light yet the light doesn’t work. A 3 way switch circuit diagram with power feed via the light switch powering a single light fixture. Oct 10, 2014 - this circuit shows a 2 way light switch with power source via light switch. From the switch you should have a three core cable such as twin and earth regardless of colours. Can you send me a diagram for that. This wire will provide constant power to the non-switched half of the receptacle. The light comes on and there is power so I do not think it is a radial. The red and black are used for hot and the white neutral wire at the switch box allows for powering a timer, remote control, or other programmable switch. tapping into a current light switch.
