Time for a switch.


This is just a cheap switch from Radio Shack. Most switches will work, just remember the tin is small, and once we get the battery holder in place there won’t be a lot of room left over. Be sure to use a sharp drill bit, go slow, and don’t push. When the bit breaks through it will want to screw into the box. Be sure you are holding the box down tightly, speed up the drill and pull back. This should cause all the burs to be on the outside of the box. Use a sharp knife to trim the burs. If the metal was bent you can also use a pair of pliers to gently flatten it out again.



When marking the holes close the lid and mark halfway between the lip and the bottom. This will help keep the washer or switch from interfering with the lid, and I think it looks better this way.
