Abstract: An electric shaving apparatus is provided which comprises a housing, a switch for activating switching cycles in which the apparatus is switched on and off, a holder for at least one external shaving member with hair-entry apertures, and an internal shaving member adapted to be driven by the external shaving member, the housing having a collecting space for shaving particles, which collecting space has a closing member with a locking mechanism, which locking mechanism comprises an actuating member, the apparatus comprising means for counting the number of switching cycles and a signalling device for signalling that cleaning of the collecting space is desirable in response to a predetermined or selected number of switching cycles. The signalling device comprises a light-emitting element in combination with the actuating member.

Abstract: A power supply circuit which maintains the voltage across a first capacitor (C.sub.1) substantially constant over a wide range of mains voltages, the capacitor (C.sub.1) energizes a motor (M) and is charged during the rising edges of the applied mains voltage in that above a specific input voltage (U.sub.min) a first transistor (T.sub.1) is turned on via a second capacitor (C.sub.2) and a first resistor (R.sub.2). When the rectified mains voltage at the output of a diode (D.sub.1) exceeds a specific value (U.sub.2) defined by a first zener diode (Z.sub.2), a second transistor (T.sub.2) is turned on. Consequently, the first transistor is turned off. When the first transistor (T.sub.1) is cut off, the first capacitor is discharged through the motor. The second capacitor is then discharged via a second zener diode (Z.sub.1) and prevents the first transistor from being turned on.
