A simple slide switch has none of the ominous effect of a Knife Switch. An evil switch for an evil project...
The switch needs to be labeled with laser etchings for maximum effect. I could not bring myself to deface it with a simple pen
Step 1: Materials required
The screws used are brass 10-24 3/4 inch in length
Step 2: Make a base.
These are 1/4 inch in thickness and about 1.5 inches wide. They come in 48 inch lengths from HD. The length is chosen by the desired characteristics of the switch and the width is 2 pine slats wide plus to pine slat edges.
Finish the inside of all pieces before joining. This is not required but the underside will look once. Assemble and glue the pieces together and sand the outside to remove any imperfections.
The resulting box should be square and sit flat on a surface.
