  1. First, sincere apology if this in not the correct NG to answer my simple
    electric circuit design requirements.



    At home in the stairway i have two 3-way switches driving one light fixture
    (120W Max.), one switch upstairs the other in the garage.

    They are wired in a power runs Switch-Switch-Fixture mode. The A.C constant
    power source is in the garage switch.



    I would like your ideas to find an elegant solution to eliminate the manual
    switching function replacing them with a one-minute timed push button.

    Ideally, i would prefer a 100% cybernetic solution; replacing the switches
    with sensors (motion? IR?). The doors are always open so I can't use them as
    triggering point.



    Thanks in advance for your help,



    Manuel

    PS: The wife thinks this is an extravagant luxury, of course she never goes
    upstairs with both arms full of grocery bags and in the dark :)
     
  2. Thanks a lot for the responses. I got the answer from Tim; Leviton has the
    sensor i was looking for.
