A switching device for an on-board electrical system of an electrically driven motor vehicle includes an electromechanical switch which is designed to connect and interrupt a supply line of the on-board electrical system. The electromechanical switch has: a stationary first switching contact, a movable second switching contact, and an actuation unit which has a mechanical force-transmitting element and a drive element. In order to switch from an open switching state to a closed switching state of the electromechanical switch, the drive element moves the transmitting element along a movement path, and the force-transmitting element moved along the movement path acts mechanically on the second switching contact and moves the second switching contact toward the first switching contact. In order to maintain the closed switching state of the electromechanical switch, the force-transmitting element applies, at the end of the movement path, a pressing force to the second switching contact for pressing against the first switching contact, without further driving by way of the drive element.
