Pull chain fixtures (posted by Tim L.)

[ASKNACHI]This question was posted on AskNACHI.org by Tim L. (from Holland mi). [/ASKNACHI]what do isolated links on a light fixture pull chian prevent

I have not found a solid answer to this question

They are the weakest link and will release the chain if pulled too hard. They keep you from breaking the original chain, some of which goes inside of the fixture and is very time consuming to fix.

They sting or other material section also isolates the metal bead pull chain from the internal switch components in the event of a fault.


Great pic!!:smiley:

I answered before I could find the pic. But I agree, it’s a keeper.

There is still no clear answer on this, what does NACHI say?
