Contact assembly for connecting electrically and mechanically a first terminal of a first apparatus to a second terminal of a second apparatus, wherein the first apparatus is a switching device and the second apparatus is a switchgear, wherein at least one of the first and the second apparatus is movable with respect to the other along a connection/disconnection direction, comprising: - a plurality of electrically conducting contact-finger-elements, each comprising a main contact portion configured for engaging said second terminal and an auxiliary contact portion for engaging said first terminal, wherein said contact-finger-elements are supported by a support frame of the contact assembly connectable to said first terminal; - one or more spring elements configured for acting on said contact-finger-elements so to urge said main contact portions against said second terminal when the first and the second apparatus are connected, wherein the main contact portions of at least two of said plurality of contact-finger-elements are shifted one relative to the other in such a manner so to engage the second terminal in subsequent moments when the first apparatus is being connected to the second apparatus by a relative movement thereof along said connection/disconnection direction, wherein said contact-finger-elements of said plurality of contact-finger-elements have same shapes and same dimensions and are disposed shifted one relative to the other, characterized in that said contact assembly is a tulip-contact-assembly, wherein said support frame comprises a first plate developing circumferentially around said central axis and forming first radial protrusions alternating with first radial slots, a second plate developing circumferentially around said central axis and forming second radial protrusions alternating with first radial slots, and a plurality of rods connecting said first plate and second plate, said at least two contact-finger-elements comprising a first resting seat to be engaged by one of the first slots and a second resting seat (18") to be engaged by one of the second slots, wherein said second plate second slots comprise primary second slots and secondary second slots (29") alternating with the primary second slots, wherein said primary second slots are shifted relative to the secondary second slots (29") along the central axis, wherein the at least two contact-finger-elements first resting seat is elongated with respect to the second resting seat (18"), and the second resting seat (18") is configured and dimensioned to match both the primary second slots and the secondary second slots (29") dimensions, such that the second resting seat (18") can be engaged by both the primary second slots and the secondary second slots (29"), and the first resting seat can be engaged by the first slots in different positions depending on which of the primary second slot and the secondary second slot (29") engages the second resting seat (18"). - a plurality of electrically conducting contact-finger-elements, each comprising a main contact portion configured for engaging said second terminal and an auxiliary contact portion for engaging said first terminal, wherein said contact-finger-elements are supported by a support frame of the contact assembly connectable to said first terminal; - one or more spring elements configured for acting on said contact-finger-elements so to urge said main contact portions against said second terminal when the first and the second apparatus are connected, wherein the main contact portions of at least two of said plurality of contact-finger-elements are shifted one relative to the other in such a manner so to engage the second terminal in subsequent moments when the first apparatus is being connected to the second apparatus by a relative movement thereof along said connection/disconnection direction, wherein said contact-finger-elements of said plurality of contact-finger-elements have same shapes and same dimensions and are disposed shifted one relative to the other, characterized in that said contact assembly is a tulip-contact-assembly, wherein said support frame comprises a first plate developing circumferentially around said central axis and forming first radial protrusions alternating with first radial slots, a second plate developing circumferentially around said central axis and forming second radial protrusions alternating with first radial slots, and a plurality of rods connecting said first plate and second plate, said at least two contact-finger-elements comprising a first resting seat to be engaged by one of the first slots and a second resting seat (18") to be engaged by one of the second slots, wherein said second plate second slots comprise primary second slots and secondary second slots (29") alternating with the primary second slots, wherein said primary second slots are shifted relative to the secondary second slots (29") along the central axis, wherein the at least two contact-finger-elements first resting seat is elongated with respect to the second resting seat (18"), and the second resting seat (18") is configured and dimensioned to match both the primary second slots and the secondary second slots (29") dimensions, such that the second resting seat (18") can be engaged by both the primary second slots and the secondary second slots (29"), and the first resting seat can be engaged by the first slots in different positions depending on which of the primary second slot and the secondary second slot (29") engages the second resting seat (18").
