Poor quality 'pattern' electrical parts, amongst other things, have been on sale since the earliest days of motoring.
It make me mad, when one reads in the trade press, yet another article where some member or chairman, of one or other of the parts distributors associations, refers to vehicle makers as mere 'parts assemblers'.
That they may be, but at least they assemble using quality parts.
So much stuff is sold as 'OE quality' when it quite obviously, is not.
The problem is that independents purchase this junk, if they refused to, the motor factors would be forced to put pressure on their suppliers to supply truly 'OE quality' parts.
We are forced to source more and more parts from main dealers, as even with the higher price, it works out cheaper than the inevitable 'come-back'
