Abstract
In a lock apparatus, a latch member is rotatable with an operating lever about the axis of a spindle, and has a first end portion mounted pivotally on the operating lever about a pivot axis transverse to the spindle axis. A switch member is operable to move between a locking position, in which the switch member engages a notch in the operating lever to prevent operation of the operating lever, and an unlocking position, in which the switch member is disengaged from the operating lever to permit operation of the operating lever. The latch member is depressible to cause pivoting movement thereof about the pivot axis and to enable an opposite second end portion thereof to push the switch member and to move the switch member from the locking position to the unlocking position when the switch member is disposed in the locking position prior to depression of the latch member.
