This design is a perfect fit for a programmable digital timer relay, which proved to be an incredibly useful little gadget. You can use it to turn electrical devices (AC or DC) on and off at programmable intervals, or when triggered by a switch. I utilized it for programming a time delay into a vapor polishing chamber project.
