What is the best way to switch power on and off every 12 hours?
I want some sort of relay or something that would switch on and off every twelve hours. It would be best to operate at 24 volts, 12 volts, or 5 volts and must allow power to pass for twelve hours, then turn off twelve hours, over and over, automatically.
If you could work with mains power as the source, eg. to a small PSU, then a plug-in timer would be the simplest solution, either the mechanical with segments, or an electronic one.
If you need it to switch something else, then you could always operate a 12v relay using a small PSU.
It may be possible to find control modules, but in single unit quantity, they would quite likely be more expensive than a retail plug-in timer.
