1. A lock apparatus, comprising:
a housing;
a spindle mounted for rotation relative to the housing;
a plunger mounted for rotation relative to the housing and extending into the spindle; and
a pushbutton mechanism, comprising:
a first component rotationally coupled with the plunger and axially coupled with the spindle;
a second component rotationally coupled with the spindle and axially movable relative to the first component and the spindle; and
a cam interface that correlates rotation of the first component with axial movement of the second component;
wherein the cam interface is configured to move the first component from an unlocking orientation to a locking orientation in response to movement of the second component from a projected position to a depressed position; and
wherein the cam interface is configured to move the second component from the depressed position to the projected position in response to movement of the first component from the locking orientation to the unlocking orientation.
