Your comment about appeal is taken... but: it is what it (prevailing) is: not mains, just 24V AC (from cheap main wall outlet transformer, no rectifiers needed). The 24V allows decent low current wires (high gauge). All timers have a battery to keep time on power interruptions (and to keep program, if not yet stored in EEPROM). First timers were electromechanical: shaded pole motor with gear related AC frequency and on/off cams... all run by 24V to avoid mains challenges... and you still can buy them... because they are extra sturdy, run (almost) for ever, and most important: 'maintainable' with basic tools (and basic knowledge).
