Electric shaving apparatus with a shaving head control means

An electric shaving apparatus comprising a housing, a shaving head, structure supporting said shaving head on said housing for free pivotal movement about a pivot axis (Z), said shaving head having at least one upper cutter and at least one lower cutter driven by a motor and in cooperative relation with said upper cutter,

• at least one actuating switch on said housing, follower structure on said shaving head,
• said follower structure of said shaving head including at least one pivot area limiting said pivot movement and at least one cam path with at least one detent location
• and control structure movable in response to said actuating switch between a first position spaced from said follower structure in which said shaving head is freely pivotable about said pivot axis and a second position in engagement with said follower structure for positively rotating said shaving head about said pivot axis to a predetermined detent location, and anchoring said shaving head in said predetermined detent location,
• said control structure including a tappet acted upon by a spring and operable by said actuating switch via pivoted lever for displacement into said detent location via said cam path, and said tappet being maintained locked in said detent location by said lever and said actuating switch.
