Longitudinally shiftable electrically conductive contact device

A contact device (1) for electrically conductively contacting, in particular flat contact partners (34), with a contact head (42), which has two contact elements (7,8), which are mounted on a common carrier (2), the contact elements (7,8) configured to longitudinally shift in a sliding direction and configured to form an electrically conductive path with the contact partner (34) while contacting the contact partner (34), wherein the contact elements (7,8) are mounted in such a way that they are configured to be moved towards one another or away from one another at least partially, characterized in that the contact elements (7,8) are formed as, in particular rigid, individual parts and are guided on the carrier (2) by means of at least one slotted guide (19,20) in such a way that when inserting the contact elements (7,8) in an insertion direction (25) towards the carrier (2), the contact elements (7,8) are moved towards one another or away from one another at least partially.
