Light contact, as your foot covers centre of rug (5)
I believe the answer is:
torch
'light' is the definition.
(type of light)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for torch that I've seen before include "source of illumination" , "Small portable battery-powered electric lamp" , "Link" , "Portable light; burn" , "Flashlight" .)
