1. A lockset with a latch-position sensing and retract slide assembly comprising:
a chassis sized to fit within a bore of a door;
a retract slide operatively connected to a door handle and a latchbolt and mounted in the chassis for movement between latch-retracting and non-latch-retracting positions;
a spring retainer;
one or more latch springs held between the retract slide and the spring retainer;
a first sensor mounted on the spring retainer; and
a first signal activator formed on or carried by the retract slide between sensor-activating and sensor-deactivating positions;
wherein when the retract slide is operated to retract the latch, the first signal activator moves between the sensor-activating and sensor-deactivating positions, thereby interacting with the first sensor to indicate a latch-retracted state.
