Abstract: Fluidic transducers of electrical signals from an electronic computer to accurately switch flow of a liquid to a utilization device. A liquid filled hollow channel (166 and 166') is accelerated along the flow axis thereof to produce a fluid control signal for a bistable fluidic switch element (112) with a cross-over type interaction channel (42) and a common outlet (45) to a pair of output passageways (147 and 148). In a preferred embodiment, electrical signals from an electronic computer (220) are supplied to a coil (170) centered by a spring (190 and 191) in a magnetic field, first in one direction of current flow and then in the opposite direction, to introduce bidirectional movement of the coil (170) and the hollow channel means (166 and 166') coupled thereto. The signals are preferably frequency modulated (205) (but may be pulse width modulated).
