Abstract
Abstract A solderless electrical connection system is shown having a main mounting board with a plurality of plated-through holes therein. A conductive electrical contact including a central section is pressed into the plated-through holes with the central section thereof flexing as it is urged into the hole and yielding to generate retention forces therein without destroying the hole. The flexing central section of the contact provides a gas seal between the plated-through hole and the contact for preventing deterioration of electrical continuity therebetween. Each end of the conductive contact may be provided with a configuration which allows electrical components to be mounted thereby or attached thereto.
