AMENDED CLAIMS received by the International Bureau on 21 July 2021 (21.07.2021)

1 . A switch assembly (1 ) comprising a housing (2), an activation button (3) slidable along an activation axis (A), and a variable capacitor (4) defining a capacitive switch having an off position and at least one on position, characterised in that said variable capacitor (4) comprises a resilient activation member (41 ) with a closed cross-section (S) supported on at least two support points (P1 , P2) and on an activation point (P3), wherein said support points (P1 , P2) are located on the opposite sides of the activation axis (A) and on one side of the longest, perpendicular to the activation axis (A) chord (C) of said cross-section (S), define a support section (B) located at least partially inside said cross- section (S), and are defined by at least one support member (42), while said activation point (P3) is located substantially on the activation axis (A); a first conductive layer (44) located on the activation member (41 ); and a second conductive layer (45) located in said off position at a non-zero distance (L1 ) from the first conductive layer (44); wherein the approach of said activation point (P3) to said support points (P1 , P2) along the activation axis causes bilateral centripetal compression of the activation member (41 ) along the activation axis (A) and centrifugal stretching of the activation member (41 ) in a direction substantially perpendicular to the activation axis (A) and displacement of said first conductive layer (44) relative to the second conductive layer (45) of the variable capacitor (4), wherein said activation member (41 ) has a hollow interior and is supported on at least two external support points (P1 , P2) and said activation point (P3) located on the other side of the longest, perpendicular to the activation axis (A), chord (C) of said cross-section (S), or on at least two internal support points (P1 , P2) and said activation point (P3) located on the same, with respect to said internal support points (P1 , P2), side of the longest, perpendicular to the activation axis (A), chord (C) of said cross- section (S), wherein 12 the change of the capacitance of the variable capacitor (4) as a function of the travel of the activation button (3) is predefined by the distance between said support points (P1 , P2), and wherein a haptic response of the switch assembly (1 ) is realized by said activation member (41 ) and is predefined by changing its dimensions and wall thickness.

2. The switch assembly according to Claim 1 , characterised in that said activation button (3a) is a part of said resilient activation member (41 ) and includes said activation point (P3).

3. The switch assembly according to Claim 1 or 2, characterised in that said activation button (3) is adjacent to said activation point (P3).

4. The switch assembly according to Claim 1 or 2, characterised in that said activation button (3) is adjacent to said support points (P1 , P2).

5. The switch assembly according to any one of Claims 1 to 4, characterised in that said resilient activation member (41 ) has a cylindrical cross-section (S) (41 , 41 b, 41c), elliptic cross-section (S), oval cross-section (S) or spherical cross- section (S) (41 d).

6. The switch assembly according to any one of Claims 1 to 4, characterised in that said resilient activation member (41 ) comprises at least two members (411 , 412), preferably connected with joints (413).

7. The switch assembly according to any one of Claims 1 to 6, characterised in that said resilient activation member (41) is made of metal and constitutes said first conductive layer (44) of said variable capacitor (4).

8. The switch assembly according to any one of Claims 1 to 6, characterised in that said first conductive layer (44a) of said variable capacitor (4a) is fixed to said resilient activation member (41 ).
