Accessory box latch for Bernina 1000 series machines

The Bernina 1000-series machines have a small accessory box that attaches to the back of the freearm. This box has a small grey clip latch that can break, allowing the box to flip open and lose its contents. This clip is a direct replacement for the OEM part. You will need to supply the spring from a common clicky ball point pen to complete the repair.
