Abstract

The present invention relates to a household appliance (1) comprising a control panel (2) having an area (A) designated thereon which provides the user to select the desired program parameters by touching, a board holder (3) situated behind the control panel (2), a circuit board (4) situated in the board holder (3), at least one touch button (7) having at least one spring (5) one end of which is fixed to the circuit board (4) and which transmits to the circuit board (4) the capacitive difference that is formed when the designated area (A) is touched and having a plate (6) which is fixed to the free end of the spring (5) so as to contact the control panel (2), and a cover (8) mounted onto the circuit holder (3) and providing the circuit board (4) to be fixed in the board holder (3). The household appliance further comprises a first element (9) that is situated on the cover (8) and that extends outwards from the cover (8) in parallel to the spring (5), and a guide (11) that provides the cover (8) to be fixed on the board holder (3) by being mounted onto the cover (8) and that has a second element (10) that forms a housing (Y) surrounding the spring (5) by joining with the first element (9) when mounted onto the cover (8).
