<p>An input assembly for a human interface device such as a keyboard comprises a first membrane (20) and second membrane (22) each having an electrical circuit provided on a surface thereof. The first and second (20)(22) membranes are arranged such that the electrical circuits of each membrane are facing each other. Means (24) is provided for permitting selective electrical connection between the electrical circuits of the first and second membranes (20)(22). An electrical connector (42) is connected to the electrical circuit of one or both of the first or second membranes (20)(22) and comprises a connection portion configured for connection to a further electrical component. Sealing means is provided which is configured to seal the membrane assembly to a further surface to form a sealed unit which seals and encapsulates both the electrical circuits of the membrane assembly and the connection portion of the electrical connector (42).</p> |
