A liquid electrical switch is disclosed that uses a plurality of droplets of
conducting
liquid to form an electrical path. In a first embodiment, at least a first voltage
differential is used to create a separation distance between two droplets. The
droplets are illustratively contained within a housing and surrounded by an immiscible,
insulating liquid. In this embodiment, the at least a first voltage differential
draws at least a portion of at least one of the droplets away from a second droplet,
thus preventing electrical current from flowing from the at least one droplet to
the second droplet. In another embodiment, the at least a first voltage differential
is changed in a way such that at least one liquid droplet is made to come into
contact with a second droplet, thus creating an electrical path between the two droplets.
