Abstract
Commutators for switching electrical or optical circuits by movement of conductive or transparent liquids derive their motion from variations in the geometry of a membrane which is a piezo-electric element. Slight variations in the length and hence curvature of the membrane in a reservoir is amplified by causing relatively large shifts of a liquid surface or interface level in a capillary system with lateral branches for the circuit connections. The membrane may be film made of oriented organic polymeric material, pref. polyvinylidene fluoride produced under conditions which enhance the phase content. Alternatively the piezoelectric switch motor may be a quartz or ceramic crystal. Suitable for switches or relays or voltage protection devices of relatively compact size, esp. for use in telephone exchange junctions etc. where the low power requirement of individual switches reduces the heat dissipation problem from large numbers of switches contained in a small volume.
