when the contactor coil is energised, the 3 ( or 4 ) sets of contacts close.
the left hand contact of the contactor is like a light switch, it turns the light on..
the middle contact is like the bypass button.. it turns the contactor on and since the contactor is on it keeps itself closed.. locking the contactor on until you interupt the power to it, which is what the timer does..
you'll have one of those "ah now i get it, it's so simple, why didn't I see it before" moments in a bit...
