<p>A power board (1) for connecting a primary power source in the form of a mains supply to a plurality of loads. The loads include a desktop computer (2), a monitor (3) for computer (2), a printer (4), and a table lamp (5). Board (1) includes a moulded plastics prismatic housing (6). An input connector, in the form of a three pin domestic plug (7) and mounted to housing (6) via a flexible insulated lead (11). A plurality of output connectors, in the form of three pin domestic power sockets (12, 13 and 14), are mounted to the housing for electrically connecting devices (3, 4, 5) respectively. A switch, in the form of a relay (15), is located within housing (6). This relay is electrically disposed between plug (7) and sockets (12, 13 and 14) and includes contacts (16) for changing between an open and closed state to respectively switch source and devices (3, 4, 5). A controller, in the form of an energising coil (17) of relay (15), is mounted, indirectly, to housing (6) for receiving a power signal from computer (2) and, in the absence of that signal, progressing contacts (16) to an open state.</p> |
