Cold effect on pull chain light?

I had a newish porcelain bulb box cover fixture in my attic. Its been below 30 degrees up there probably for a few days.

Pulling the chain, the bulb did not light. Swapped bulb same thing. After pulling a few time it finally lit.

I then swapped out the fixture with an exact replacement (Leviton brand) and the new one lit as it should on the first pull.

Would cold have any effect on the switch in those pull chain fixtures?

The pull chain simply operates a mechanical switch the same as a toggle wall switch. It is either on or off.

Cold will affect some bulb types, especially fluorescent.

I should mention these were incandescent bulbs, they are not the issue. So just a bad switch then? Seems unlikely which is why I felt inclined to post about it.

The new fixture, an exact replacement, had a different "feel" when pulled... more pronounced or a strong click if that makes any sense .... perhaps I was pulling the old chain at an angle or the chain was tangled or something....

the other lights on that circuit, albeit inside the house, appear ok.

From my experience the switch in a porcelain lamp holder seldom lasts more then a couple of years.
