A device for use in a non-ablative surgical procedure for improving the appearance of skin tissue of a patient by applying RF energy thereto, the device comprising: (a) a handpiece having an electrical conductor configured for receiving RF energy from a generator when activated, the handpiece supporting a non-ablative electrode having an active surface to be brought into contact with the patient's skin to apply the received RF energy to the skin when the generator is activated, wherein the handpiece comprises: (b) first switch means, characterised in that said switch means is further configured for electrically connecting the electrode's active surface to the electrical conductor configured for receiving RF energy only when and while the active surface is in actual contact with the patient's skin, wherein the first switch means comprises a first electrically conductive member coupled to the electrode and a second electrically conductive member coupled to the electrical conductor configured for receiving RF energy, whereby the first electrically conductive member is longitudinally movable relative to the hand piece in correspondence with the electrode surface between an RF-disconnected position and an RF-connected position, wherein the first electrically conductive member and the second electrically conductive member are configured to be electrically coupled with each other in the RF-connected position such that the electrode's active surface is electrically coupled to the electrical conductor configured for receiving RF energy in the RF-connected position and electrically isolated from the electrical conductor configured for receiving RF energy in the RF-disconnected position; and (c) a biasing member configured to urge the electrode toward the RF-disconnected position, wherein the biasing member is electrically isolated from the second electrically conductive member in the RF-disconnected position.
