ABSTRACT:
An electrical switch (116) is disclosed having multiple inputs (214) and binary switches (312) operable to switch a signal from an input (214) via respective amplifiers (310). Amplifiers (310) are continuously operable and are provided with an auxiliary switching circuit (412) which provides the amplifier with a fixed voltage input signal when the associated input (214) is not selected. Response time upon selection of an amplifier (310) and crosstalk from any non-selected amplifier is minimised.
