Programmable Timer Relay Case

This design is a case for a digital programmable timer relay, which turned out to be a handy little tool. You can use it to turn electrical devices (AC or DC) on and off at programmable intervals, or when activated by a switch.
I used it for programming a time delay into a vapor polishing chamber project.
