Specifically, tired springs on the socket contacts, same on the fuse holder, very small actual contact area which is vulnerable to contamination, so raising its resistance.  Further, very small metal content, of sometimes doubtful quality, so that any generated heat rapidly increases temperature, to the detriment of the contact springs, and leading to a thermal runaway.</p></blockquote><p></p>
