Abstract
The invention relates to a shaving apparatus comprising a housing (1) and at least one hair-cutting member (6). In order to prevent a user from irritating and injuring the skin during shaving, as far as possible, the shaving apparatus comprises means for warning the user when a given preset force is exceeded. The means can be, for example, one or more sensors which measure the force between the hair-cutting member and the housing during shaving. The sensor can be, for example, a Hall sensor (21), which is secured to the housing and which cooperates with an annular magnet (19), which is secured to a coupling pin (11) for driving the rotary hair-cutting member (6). The invention can also be used in wet-shavers.
