The longitudinal extension direction of the bushing contact runs essentially perpendicular to the conductor insertion direction from the busbar piece. The bushing contact is designed to receive the contact pin perpendicular to the longitudinal extension direction of the bushing contact and to receive the contact pin in the longitudinal extension direction of the bushing contact. ## Claims ### Claim 1 A contact insert for a connecting terminal, the contact insert comprising: a busbar piece; and a clamping spring to clamp an electrical conductor in a conductor insertion direction, wherein the busbar piece and the clamping spring form a clamping point for the electrical conductor to be clamped, wherein the contact insert has a bushing contact for receiving a contact pin, wherein the longitudinal extension direction of the bushing contact runs essentially perpendicular to the conductor insertion direction of the busbar piece, and wherein the bushing contact is adapted to receive the contact pin substantially perpendicular to the longitudinal extension direction of the bushing contact and adapted to receive the contact pin in the longitudinal extension direction of the bushing contact. ### Claim 2 (depends on 1) The contact insert according to claim 1, wherein the bushing contact has two contact arms that project from the busbar piece in the longitudinal extension direction of the bushing contact. ### Claim 3 (depends on 2) The contact insert according to claim 2, wherein the contact arms of the bushing contact are oriented conically with respect to one another or in a plane extending substantially perpendicular to the longitudinal extension direction of the bushing contact. ### Claim 4 (depends on 3) The contact insert according to claim 3, wherein the contact arms form a receptacle substantially perpendicular to the longitudinal extension direction of the bushing contact and a receptacle in the longitudinal extension direction of the bushing contact for the contact pin. ### Claim 5 (depends on 1) The contact insert according to claim 1, wherein the busbar piece has a contact opening for receiving a bridge and/or a switch spring. ### Claim 6 (depends on 5) The contact insert according to claim 5, wherein the bridge is arranged in the contact opening, and wherein the bridge electrically conductively connects the contact insert and a second contact insert. ### Claim 7 (depends on 1) The contact insert according to claim 1, wherein a conductor insertion contour for guiding the electrical conductor projects from the busbar piece. ### Claim 8 (depends on 1) The contact insert according to claim 1, wherein the busbar piece and the bushing contact are formed in one piece. ### Claim 9 (depends on 1) A connecting terminal comprising: an insulating material housing; and a contact insert according to claim 1, wherein the insulating material housing forms a conductor stop for the electrical conductor to be connected. ### Claim 10 (depends on 1) A switch spring comprising: a connecting web for electrically conductive contacting two contact inserts according to claim 1; a contacting area for contacting the first contact insert; and a switching arrangement for contacting the second contact insert, the contacting area and switching arrangement being arranged on the connecting web, wherein the switching arrangement has an actuating section and is arranged to release the contacting between the switching arrangement and the second contact insert by applying force to the actuating section. ### Claim 11 (depends on 10) The switch spring according to claim 10, wherein the switching arrangement has a bearing portion for bearing on a housing and/or contact insert, wherein the bearing portion extends into the operating portion and wherein a contacting portion for contacting the second contact insert is arranged on the operating portion. ### Claim 12 (depends on 10) The switch spring according to claim 10, wherein at least one tab is arranged on the actuating section, wherein the tab interacts with a contour of a pin strip such that the contact between the switching arrangement and the second contact insert is released.
