I am planning a 110 v ac circuit whereby I will have two timers attached to the source power. These two timers will control lights (plugged or hard wired) on different schedules.

I want to wire a switch to each (set of) lights so that the lights will run on either timer A cycle or timer B.

A nice grounded 3-wire circuit diagram will do. I plan to branch each circuit tow four switched lighted sub-circuits.

Also where can I find panel-mountedhard wired timers for my implementation?

Thank you.
