Boeing issues alert due to 787 engine fire switch failures
Boeing has issued an alert to airlines using its flagship B787 Dreamliner, warning that the switch used to extinguish an engine fire has failed in a “small number” of instances. The switch also severs the fuel supply and the hydraulic fluid to prevent flames spreading.In its alert to airlines, Boeing warns that long-term heating can cause the fire switch to stick in the locked position so it can’t be used to release the two fire extinguishers in each engine.

They don't make em' like they used to...
Chinese parts/components cut cost at the same cut safety
Spot on pal, spot on. There's always been the bloke who'll con ya' out of an honest quid, nowadays there are bloody airworthiness processes and plane makers themselves cutting corners. Corporate greed.
Dont they inspect these parts,if they do and install. Then you tell me.
Incoming parts inspection at manufacturing facilities cannot possibly involve 100% inspection down to each every switch on an airliner. Quality inspection in the aircraft manufacturing industry often involves "sampling", and also a reliance upon past vendor performance. Please believe me, as I am an expert on the business processes instituted at manufacturing facilities, including quality inspection of incoming purchased and/or manufactured parts. I do not represent Boeing or any other aircraft or aircraft parts manufacturer at this time.
How much could this switch possibly cost? Is there any quality control left at Boeing?
The switch in question in part number 010-2310445-70. It's cost $1147.83 according to Boeing's ERP system. The price of the switch is $1521.60 if you purchase it as a spare part and your customer record shows you to be part of the "AL2330" customer segmentation within their customer hierarchy. Yes, Boeing is entitled to make this relatively small profit on the switch. Also, yes, Boeing has a world-class quality control system. Please do a little research on manufacturing quality control before asking such inane questions. Boeing products are among the best aircraft mankind has ever produced, based upon their stellar safety record. Now please go back to be whipped up by the news media, you sheep.
