Where can I buy a new drop-in Bobbin case electric contact spring? On removing the drop-in bobbin case I broke 'the spring'. 'The spring' is pictured well in many articles but;

No explanation of what the 'electrical contact' spring actually does. (Other than a guide to inserting the bobbin correctly).
No name of the part other than 'spring'.
I cannot find it in the parts manual and wonder if anyone can tell me how I could find more details about it, so that I can order this. Sources would also be welcome.

(My machine is 2 weeks old and has produced nothing but birds nests, 2 broken and 1 bent needle!)
The reason you can't find any part numbers or additional information is because that part of the machine is not considered a &quot;user serviceable&quot; area. As you appear to be inexperienced with sewing machines in general, I would strongly recommend that you not attempt to repair this part yourself. There are many sewing machine repair shops available that can do the repair for you.
