The cooling member may be connected to the bracket such that the contactor is indirectly connected to the cooling member via the bus bar and the bracket. A method of assembling an electrical assembly may include providing a bracket and one or more contactors, inserting the one or more contactors into the bracket, disposing a flexible circuit at least partially on and/or in the bracket, electrically connecting the flexible circuit with the one or more contactors, connecting a bus bar assembly with the one or more contactors, connecting the bus bar assembly with the bracket, disposing a cooling member on or about the bracket, and/or connecting the cooling member with the bracket. ## Claims ### Claim 1 An electrical assembly, comprising: a contactor; a bus bar connected to the contactor; a bracket connected to the bus bar; and a cooling member connected to the bracket such that the contactor is indirectly connected to the cooling member via the bus bar and the bracket. ### Claim 2 (depends on 1) The electrical assembly of claim 1, wherein the contactor is fixed directly to and in contact with the bus bar; the bus bar is fixed directly to and in contact with the bracket; and the bracket is fixed directly to and in contact with the cooling member. ### Claim 3 (depends on 1) The electrical assembly of claim 1, wherein the cooling member includes an at least partially hollow body configured to receive a cooling fluid. ### Claim 4 (depends on 1) The electrical assembly of claim 1, wherein the contactor includes an electrical terminal disposed at or about a first end of the contactor; and a second end of the contactor extends beyond the bracket such that the second end of the contactor is exposed. ### Claim 5 (depends on 4) The electrical assembly of claim 4, wherein an exposed portion of the contactor comprises metal. ### Claim 6 (depends on 1) The electrical assembly of claim 1, wherein the contactor includes a radially-extending flange in contact with a lip of a through aperture of the bracket. ### Claim 7 (depends on 1) The electrical assembly of claim 1, including one or more additional contactors connected to the bracket; wherein the one or more additional contactors are connected to respective additional bus bars that are connected to the bracket such that the one or more additional contactors are indirectly connected to the cooling member via the respective additional bus bars and the bracket. ### Claim 8 (depends on 7) The electrical assembly of claim 7, including a flexible circuit electrically connected to the contactor and each of the one or more additional contactors. ### Claim 9 (depends on 8) The electrical assembly of claim 8, wherein the flexible circuit is disposed substantially between the bracket and the cooling member. ### Claim 10 (depends on 9) The electrical assembly of claim 9, wherein the flexible circuit includes a respective pair of integrated eyelets electrically connected to control terminals of the contactor and the one or more additional contactors. ### Claim 11 (depends on 10) The electrical assembly of claim 10, wherein contactor includes a first contactor terminal connected to the bus bar; the contactor includes a second contactor terminal connected to a second bus bar that is connected to the bracket; and the first contactor terminal, the second contactor terminal, and control terminals of contactor extend from a first end of the contactor in substantially the same direction. ### Claim 12 (depends on 1) The electrical assembly of claim 1, wherein the bracket includes a through aperture and the contactor is disposed in the through aperture. ### Claim 13 (depends on 12) The electrical assembly of claim 12, including one or more additional contactors; wherein the bracket includes a respective through aperture for the one or more additional contactors. ### Claim 14 (depends on 1) The electrical assembly of claim 1, including a top cover covering a pair of control terminals and a vent of the contactor; wherein the top cover includes an insulating wall disposed between contactor terminals of the contactor. ### Claim 15 A method of assembling an electrical assembly, the method comprising: providing a bracket and one or more contactors; inserting the one or more contactors into the bracket; connecting a bus bar assembly with the one or more contactors; connecting the bus bar assembly with the bracket; disposing a cooling member on or about the bracket; and connecting the cooling member with the bracket. ### Claim 16 (depends on 15) The method of claim 15, wherein the cooling member is connected with the bracket such that the one or more contactors are indirectly connected to the cooling member via the bus bar assembly and the bracket. ### Claim 17 (depends on 15) The method of claim 15, including disposing a flexible circuit at least partially on and/or in the bracket prior to connecting the bus bar assembly with the one or more contactors; and electrically connecting the flexible circuit with the one or more contactors; wherein the bus bar assembly is connected with the one or more contactors such that portions of the flexible circuit are disposed directly between the bus bar assembly and the bracket. ### Claim 18 (depends on 15) The method of claim 15, wherein disposing the cooling member on the bracket includes inserting the bracket, the flexible circuit, the bus bar assembly, and the one or more contactor at least partially into a recess of the cooling member. ### Claim 19 (depends on 15) The method of claim 15, wherein at least one contactor of the one or more contactors is inserted into the bracket such that an exposed portion of the contactor is not covered by a sleeve portion of the bracket. ### Claim 20 (depends on 15) The method of claim 15, wherein the bus bar assembly is fixedly connected with the one or more contactors by one or more first fasteners; the bus bar assembly is fixedly connected with the bracket via one or more second fasteners; and the cooling member is fixedly connected with the bracket via one or more third fasteners.
