Replacement for the lid latch slider inside the upper lid of the Zojirushi CD-WBC30/40 water boiler (the part under the "Lid Lock" flat hook). The original slider was lost, so this one was reverse-engineered from a 3D scan of the lid and caliper measurements of the pocket.
STATUS: prototype v7, untested against the boiler body. The hook length and its catch profile are placeholders until the body catch is measured.
HOW IT WORKS
The slider lies flat on the pocket floor between the two islands and is held down by the two overhanging tabs.
- The original coil spring (34.6 mm free length, 7.4 mm outer diameter) sits in the centre tunnel of the slider and pushes against the rear wall of the pocket. In the closed state it is compressed to 21.5 mm.
- The nose of the lid flap pushes the block on top of the slider backwards by about 4 mm, the hook retracts from the front rim opening and the lid is released.
INSTALLATION
Put the spring into the tunnel from the rear.
2. Lower the slider into the pocket shifted about 8 mm backwards from its working position: the two edge notches let the plate pass the tabs.
3. Push the slider forward: the hook goes through the rim opening and the tabs now sit over the solid edges of the plate.
