Electric shaver with indicator of maximum deflection of cutting head

摘要

The appliance receives current or voltage from a source (101) via the bearing (102) about which the head carrier (105) is pivotable with a contact (106) having two angled arms (107,108). The ends of the arms engage respective contact pins (109,110) wired to light-emitting diodes (113,114). The signal can be given alternatively by a change in speed of the driving motor, with either an abrupt and audible reduction or a cyclic variation at a particular frequency, when a defined maximum deflection is exceeded.
