The patent relates to an improved electrical contact configured to provide more accurate electrical potential readings. Electrocardiograms and electroencephlograms, for example, require that a monitoring electrode be firmly held on a creatures body to give valid readouts. To that end, a suction cup is cast integrally from a resilient compound to create a sufficient suction when it is pressed against a surface. An annular shoulder portion molded in the suction cup engages a projection from the electrode and holds the electrode firmly on the surface. The suction cups relatively wide lip ensures the continued creation of the vacuum while the biasing force of the annular shoulder on the extension ensures responsive operation over a prolonged period of time.
