A combined lock/actuator for actuating a driven member from a primary position to a secondary position when the lock/actuator is locked and then maintaining the driven member in the secondary position until the lock/actuator is unlocked, said lock/actuator comprising:

• a lock barrel having a longitudinal axis, an opening extending along the axis, and a recess;
• a lock plug operably mounted directly in said opening, said plug rotatable within said opening between an actuation position and a release position and translatable relative to said opening along said axis between a first position where a driven member is in a primary position and a second position where a driven member is in a secondary position while the plug is operably mounted in said opening;
• and
• an axial catch mounted on said plug, said catch engaged with said recess when said plug is in both the actuation position and the second position, said catch disengaged from said recess when said plug is in said release position, said catch mounted on said plug for movement between an extended position with said catch engaging said recess and a retracted position with said catch disengaged from said recess.

A combined lock/actuator for actuating a driven member from a primary position to a secondary position when the lock/actuator is locked and then maintaining the driven member in the secondary position until the lock/actuator is unlocked, said lock/actuator comprising:

• a lock barrel having a longitudinal axis, an opening extending along the axis, and a recess;
• a lock plug rotatable within said opening between an actuation position and a release position and operably translatable within said opening along said axis between a first position where a driven member is in a primary position and a second position where a driven member is in a secondary position, said plug including an arcuate groove;
• and
• an axial catch mounted on said plug, said catch engaged with said recess when said plug is in both the actuation position and the second position, said catch disengaged from said recess when said plug is in said release position, said catch being in the form of a generally C-shaped clip that is mounted in said groove.

A push button switch lock capable of activation in a locked, actuation position and incapable of deactivation in the actuation position, said switch lock comprising:

• a lock barrel having an opening extending along a longitudinal axis and a recess in said opening;
• a lock plug mounted directly in said opening, said plug rotatable within said opening between an actuation position and a release position, said plug translatable within said opening over a fixed axial displacement along the longitudinal axis between a first position and a second position;
• an axial catch mounted on said plug and engaged with said recess when said plug is in both the actuation position and the second position, said axial catch disengaged from said recess when said plug is in said release position, said catch mounted on said plug for movement between an extended position with said catch engaging said recess, and a retracted position with said catch disengaged from said recess;
• a switch mounted to said barrel, said switch having an activated position and a deactivated position;
• and
• means cooperating between the switch and the plug to place the switch in the activated position when the plug is in the second position and in the deactivated position when said plug is in the first position.
