Disclosed are keyboards and keyboard switches sensitive to touch, including, hover and pressure. The keyboard switches have transmit and receive antennae that are spaced apart such that no portion of the transmit antenna touches any portion of the receive antenna. The keyboard switches are arranged in logical rows and logical columns such that each of the keyboard switches is associated with one row and one column. Signal emitters are conductively coupled to the transmit antennae for each of the keyboard switches associated with each of the rows, and each of the signal emitters are adapted to cause each of the transmit antennae to transmit one or more source signals. Receivers are coupled to the receive antennae for each of the keyboard switches associated with each of the columns, and each of the receivers are adapted to capture a frame of signals present on the coupled receive antennae. A signal processor adapted to determine a measurement from each frame, corresponding to an amount of the source signals present on the receive antennae during a time the corresponding frame was received. The signal processor further adapted to determine a keyboard switch touch state from a range of touch states based at least in part on the corresponding measurement.
