Step 10Preparing the Battery Holder
Slide small pieces of heat shrink tubing along the both leads of the battery holder. Push them carefully into the holes of the holder and shrink into place. These provide some degree of protection for the wires. (This instruction is duplicated on the Preparing the Toggle Switch page.) Cut the black wire to length and solder into the appropriate hole on the PCB. The red wire is soldered directly to the toggle switch; see instructions on that page for how to proceed.
In past projects I have cut the retaining tabs off of the battery holder. Having done this on the prototype, I now regret it. The battery does not want to stay tightly in place. Leave the tabs to start and remove them only if you have trouble getting the battery out. Despite saying this, the picture shows a battery holder with the tabs cut off. This is because I scavenged it from another project.
