An electrical connection across a peripheral surface through a sealed enclosure (34A) in a radial plane between a tubing hanger (5) and a surrounding support member (3). The connection includes a coupling element (17) in the tubing hanger (5) and an electrical contact supporting shuttle (20) which can reciprocate from a position wholly within the support member (3), across the interface and into electrical connection with the coupling element (17), without producing any movement of a conductor cable (9, 10, 11, 15) leading into a sealed enclosure (34A) within the support. In certain embodiments, the shuttle (20) is driven by threaded engagement with a rotatable drive sleeve (30) and includes a sleeve (21) that is reciprocated over a stationary power core (22). The shuttle (20) is also filled with a dielectric gel (26) contained within a flexible bladder (25). A sensor contact (35) can be used to indicate full retraction of the shuttle (20).
