A conductive paste based on an elastomer of the polyoxypolyolefin type or on a member of the polyolefin family is described, provided with an admixture of conductive particles for the production, in the electronics industry, of a sealing element, of a contact element or of a heat-conduction element. The electric element includes two anode electrodes and two cathode electrodes and has relatively low impedance in a frequency range between 1\xd710\u22125 to 10 GHz. A spring may bias the latch to engage with the daughter board and to lock the daughter board to the base and the seat of the retainer.
