Abstract
The mechanism comprises a pivotally mounted lever member having a pushbutton portion and having its free end adapted for engagement of the actuator in a panel-latching system. An annular lock cylinder is mounted transversely underneath the pushbutton portion and is provided with a slot adapted to accommodate a portion of the pushbutton portion. One end of the cylinder has its surface formed into a cavity having a predetermined pattern whereby the lock cylinder may be rotated only by engagement with a tool adapted to engage the patterned cavity. The cylinder is rotatable to at least first and second positions whereby in the first position, the lever member is allowed to engage the actuator and is prevented from engagement therewith in the second position.
