1. An electrical switching assembly comprising:

  • a first non-conductive substrate having a surface;

    a layer of dielectric material deposited upon the surface of the first non-conductive substrate and patterned to create heater cavities, a liquid metal channel and passages connecting the heater cavities to locations along the liquid metal channel;

    a second non-conductive substrate having a surface;

    a layer of adhesive deposited on the surface of the second non-conductive substrate and patterned to match the pattern of the layer of dielectric material; and

    the surfaces of the first and second non-conducting substrates facing each other and being brought into contact through the intervening layer of dielectric material and the layer of adhesive.
