A disconnector unit for a medium voltage application, with a conductive pen inside a housing. The conductive pen is moveable between an operational position in which an electrical contact is provided between a first terminal and a second terminal positioned inside the housing, and an off position in which no electrical contact is present between the first terminal and the second terminal. The conductive pen includes a first actuating part inside the housing, optionally, in the form of a magnet. The disconnector unit further includes a second actuating part positioned outside the housing, wherein the first actuating part and second actuating part form a non-mechanical link.
