  • FIG. 2 shows an exploded view of interacting components, by means of which the slide switch 2, which is displaceably mounted on the front F of the housing 1 and is provided with a long hair cutting system L, from the actuation switch 30 from an off position - see FIG. 1 - into at least one operating position - see FIG. 6 - can be brought.
  • a plurality of U-shaped guide elements 60 are arranged on the front side F of the housing 1, in which the slide switch 2 is held displaceably by means of webs 61 engaging in these guide elements 60.
  • a bearing pin 27 provided on the front side F serves as a pivot bearing for the gear element 7 provided with a corresponding pivot bearing 11.
  • the gear element 7 has a control cam 12 opposite to the pivot bearing 11.
  • a coupling element 20 for coupling to one end of a spring element 19 is provided between the control cam 12 and the pivot bearing 11 on a line S connecting them, see FIG. 3.
  • the opposite end of the spring element 19 is coupled to a control element 13 arranged on the slide switch 2 and engaging in the control cam 12 of the transmission element 7.
  • a locking arm R with three locking positions 24, 25, 26 lying in a row is also formed on the gear element 7.
  • the actuation switch 30 is formed by the actuation element 31 and the link 3.
  • Two clip elements 33 are provided on the actuating element 31. These two clip elements 33 of the actuating element 31 pass through guide slits 4 provided in the slide switch 2 and extending parallel to the vertical central axis V, as well as the two clip openings 34 provided in the link 3, in order to use the clip connection to actuate the element 31 and the link 3 to form a switch 30 Unite assembly.
  • the link 3 is essentially U-shaped with two arms 35, 36, 37 running parallel and one transverse to the vertical central axis V.

  • a coupling element 17 arranged on the gear element 6 serves as a counterbearing for a spring element 16 coupled to the link 3, for example on the transverse arm 36.
  • the arrangement of the gear element 6 in the transverse arm 36 of the link 3 by means of the pivot bearing engaging in the pivot bearing 9 8 is made such that this bearing is positioned slightly next to the vertical center axis V.
  • the position of the locking element 14 on the gear element 6 is such that the vertical center axis V runs through the locking element 14.
  • the latching element 14 assumes a position on the vertical center axis V in all switching positions of the actuation switch 30.
  • Fig. 3 shows the "off" position of the dry shaver.
  • the lower edge 21 of the slide switch 2 and the lower edge 22 of the link 3 rest against the stop 23 in the housing 1, see FIG. 2.
  • the locking element 14 and the locking positions 24, 25, 26 are located on the vertical central axis V of the housing 1.
  • the locking element 14 is under the action of the spring element 16 in the locking position 24 of the gear element 7.

  • the locking element 14 snaps into the locking position 25.
  • an electrical microswitch not shown in the drawing, which is provided for switching the electrical drive of the dry shaving apparatus in the housing 1 on and off, is actuated by the link 3.
  • the position of the gear element 7 and thus the position of the long hair cutting system L has not changed.
  • the long hair cutting system L is now located above the shear plane of the short hair cutting system K and can advantageously be used in this position for trimming hair contours.
  • the gear element 7 acts between the actuating switch 30 and the slide switch 2 as a transmission lever.
  • the displacement path of the slide switch 2 is approximately twice as large as the displacement path of the actuating switch 30.
  • the long hair cutting system L is displaced by 24 mm.
  • the control curve 12 essentially has a triangular basic shape, the two side walls 40, 41 running adjacent to the line S being slightly curved are so that in the respective pivoting direction of the gear element 7, the pushing force from the respective side wall 40, 41 largely vertical, i. H. acts in the direction of arrow B on the control element 13. This results in a reduction in the actuating force to be applied to the actuating switch 30 of the dry shaving apparatus in comparison with an elongated control cam which can also be used and which has parallel side walls.
  • the opening 42 provided at the end of the control cam 12 opposite the bearing pin 27 in an imaginary extension of the arcuate side walls serves to simplify and facilitate the assembly of the gear element 7 on the bearing pin 27 and the coupling with the control element 13.
