| An electrical relay array using conducting liquid in the switching mechanism. The relay array is amenable to manufacture by micro-machining techniques. Each element of the relay array uses an actuator, such as a piezoelectric element, to cause a switch actuator to insert into a cavity in a static switch contact structure. The cavity has sides and a pad on its end that are wettable by the conducting liquid. The cavity is filled with the conducting liquid, which may be liquid metal. Insertion of the switch actuator into the cavity causes the conducting liquid to be displaced outward and come in contact with the contact pad on the switch actuator. The volume of conducting liquid is chosen so that when the actuator returns to its rest position, the electrical contact is maintained by surface tension and by wetting of the contact pads on both the static switch contact structure and the actuator. When the switch actuator retracts away from the static switch contact structure, the available volume for conducting liquid inside the fixed switch contact structure increases and the combination of the movement of the conducting liquid into the cavity and the contact pad on the switch actuator moving away from the bulk of the conducting liquid causes the conducting liquid connection between the fixed and moving contact pads to be broken. When the switch actuator returns to its rest position, the contact remains electrically open because there is not enough conducting liquid to bridge the gap without being disturbed. The high frequency capability is provided by the additional conductors in the assembly, which act to make the switch a coaxial structure. | ||||||

| A multilayer switching assembly for switching high frequency signals has MEMS structures on a ceramic substrate having a top surface, a bottom surface and a plurality of insulating layers. The insulating layers are separated by a first conductor and a second conductor. The first conductor is connected to a ground potential. The second conductor is separated from the first conductor by one of the insulating layers. The second conductor presents a specific impedance (50 ohms) with respect to the first conductor to high frequency signals traveling on the second conductor.64 MEMS structures are mounted on the top surface. Each MEMS has an input, an output, and a control. The input connected to the second conductor. The output is connected to a coplanar waveguide placed on the top surface. The control is connected to the bottom surface.The input to each MEMS is electrically shielded from the output and from the control by a third conductor connected to the first (grounded) conductor. The third conductor traverses one or more of the insulating layers thereby acting as a shield and precluding the high frequency signals presented to the input from propagating to the output and to the control. The 64 MEMS are arranged in a square 8 by 8 matrix, as well as their controls. High frequency inputs and outputs to be switched by the MEMS are placed on the periphery of the substrate to further enhance the separation of signals. Terminating resistors (50 ohms) are also placed near the periphery. | ||||||

In the quiescent state, each cantilever or simply suspended bridge structure contains an upper electrode which forms one part of the switch, while another conducting layer, the lower electrode at the bottom of the well of the individual sensor, forms the other part of the switch. | ||||||
