The apparatus comprises a lever (33) for contacting an actuation source and for contacting the switchable valve train component (80); and a biasing means. The biasing means contacts the lever (33). In use, the biasing means becomes biased by the lever (33) when the actuation source moves the lever when the actuation source attempts to actuate the switchable valve train component (80), via the lever (33), when the switchable valve train component (33) is in an un-activatable state. The biasing means causes the lever to activate the switchable valve train component (33) when the switchable valve train component (33) is in an activatable state again. Also disclosed is a valve-train assembly.
