Yes, it is necessary to pull a yellow wire into the switch box; If there is no live wire, you can pull a live wire into the double-open switch box, so that the switch is single-linked, dual-control is OK, single-link is the switch control light, ventilation fan, and dual-control share a live wire.
Why don't I see anything else? Can you send a picture, let me also see, in addition to the capacitor and switch, I really haven't seen anything else, you won't be talking about the insulating clamp of the wire.
Open the cover and you can see the fixed gong wire, just unscrew it, it's very convenient, and you should buy it the same size.
No, the exhaust vents of the exhaust fans have a simple one-way valve cover that can only be opened outward.
L is connected to a live wire, and then this live wire is connected to L1 and L2 respectively, so that you can control two lights at the same time.
