    The single pole switch, (gate keeper), that is wired in series on the load side of the paralleled time clock contact/manual timer switch contact and the contactor/s coil/s.

    Control circuit hot L1 >>> paralleled time clock and manual timmer contacts >>> SPST manual power off switch >>> Contactor/s coil/s >>> other side of coil/s to L2.

    Lets re-open this can of worms!! SO.. had a walk through with the client. All was well (thanks to a little help from this site) HOWEVER, they have added some things and made some changes. So lets see how you guys would tackle this! What they would like to see now is:

    Exterior lights on a timeclock. Done. No change needed.

    Interior lights: all interior lights on a timeclock set to desired hours.

    A master switch (they would like to use a 7 day programmable in wall timer with a manual override option) to override all interior lights. ( i see no need for a separate timeclock as these do both functions?)

    Bonus: the janitors closet to be on a countdown timer as well that overrides all interior lighting while they clean. But will automatically turn off after, for example, 4 hrs.

    That last one is cute. Not out for everybody to play with and when the cleaning crew turns on the closet lights it automatically turns on the general interior.
    Only one time switch in one janitor's closet? Will the rest (if any) have individual room switches?

    Would the seven day time clock allow both on and off override? Should it?
    How will occupancy sensors (if any) fit into this scheme?

    Now that you have re opened your can of worms.....

    This is all very doable, the degree of difficulty is depends on how this place is wired and how things are switched already.
