A window includes: a window frame having an opening defined therein through which an outdoor space and an indoor space communicate with each other; a pair of sashes slidably disposed in the window frame and that slide along an opening direction and a closing direction opposite to the opening direction; variable transmittance windowpanes configured to be fitted in the sashes to open and close the opening together with the sashes depending on sliding of the sashes; the variable transmittance windowpanes having a transmittance variable by electrical connection; first conductive members disposed on the sashes and electrically connected with the variable transmittance windowpanes to supply electric power to the variable transmittance windowpanes; and a second conductive member electrically connected with the first conductive members to supply the electric power to the first conductive members from outside the window frame.

A slidable current collector has an array of terminals with carbon brushes for contacting conductor rails to deliver electrical power to a moving work machine. The terminals have upper sections with a conductive post, lower sections that include a reservoir of liquid metal, and bladders that connect the upper sections with the lower sections. Magnets surround outer shells of the terminals. Fluid above a threshold pressure fed into the bladders holds the upper sections apart from the lower sections and forces the magnets away from the conductor rails. Fluid below the threshold pressure allows the magnets to clamp the terminals to the conductor, lowers the conductive post into the liquid metal, and urges the carbon brushes against the conductor rails. The bladders provide a fluid suspension distributed across the array of terminals, enabling consistent electrical contact and wear for the carbon brushes.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity.
