  • the device 10 or the contact element 13 or the slider 14 adjusts itself to a zero position defined by the predetermined closing position, each time adjusted by the analogous predetermined travel position of the slider 14.
  • the resulting resting closed position of furniture part 4 is shown by the Figures 4 and 5 , i.e., after the drive unit of the furniture part drive 3 is switched off. Accordingly, when the slider 14 reaches its zero position, in which the drive unit or the electric motor is switched off, the contact surface 13a of the contact element 13 is in contact with the inside of the inner surface 4a of the furniture part 4.
  • a plane of the furniture part 4 defined by the flat inner surface 4a is aligned parallel to the plane E of the front of the furniture body 2 (see figure).

  • Fig. 8 of a possible maximum movement path of the slider 14 relative to the base body 12 of, for example, 5 millimeters.
  • Figures 6 and 7 Figure 1 shows a triggering process by pressing with a force A on the outside of the furniture part 4 according to a touch-latch system to trigger a switching command to switch or turn on the drive unit of the furniture part drive 3.
  • the furniture part 4 is thereby pivoted slightly inwards in the closing direction S1, and a force K acts from the inside 4a on the contact surface 13a, moving the contact element 13 and the slider 14 in the direction of R2, for example, as shown.
  • Fig. 10 .
  • this signal is processed by, for example, a microcontroller unit of the control unit, and the drive unit of the furniture component drive 3 is activated.
  • the furniture component 4 is then moved or opened in the opening direction opposite to direction S1.
  • the total possible actuation stroke of the slider 14 in the direction of R2 is, for example, 1.5 millimeters, which corresponds to a closing gap SP between the inner surface 4a and the plane E when the furniture component 4 is closed, according to... Fig. 5 correlated.
  • the device 10, or analog push button comprises an electrical line 22 through which the sensor 23, designed as a Hall sensor and mounted on the base body 12 between the stops 15 and 16, is electrically supplied.
  • the sensor 23 is designed as a Hall element or Hall sensor.
  • the device 10 also has a magnet arrangement 24 with two permanent magnets 25 and 26 spaced apart from each other in the direction of R1 and R2, respectively, between which the sensor 23 is located in the direction of movement of the slider 14.
  • the two permanent magnets 25 and 26, with their magnetic fields M1 and M2 are aligned with their same magnetic poles south to south, or alternatively north to north, so that a change in the position of the slider 14 along its path of movement causes a change in the signal voltage or Hall voltage detectable at the sensor 23, which serves to trigger a switching command.
  • a trigger command is detected and processed by the control unit to trigger the switching command for the drive unit.
  • the furniture part 4 is driven in the opening direction opposite to the closing direction S1, or pivoted upwards until a predefined open position of the furniture part 4 on the furniture body 2 is reached.
  • the position of the furniture part 4 is then determined according to... Fig. 1 run over Towards S1.
