Abstract

Electrical contacting surfaces are disclosed having numerous electrically conductive substantially spherical protrusions. These contacting surfaces may be used repeatedly in low voltage applications. The numerous electrically conductive substantially spherical protrusions provide points of high pressure thereby forming multiple parallel electrically conductive pathways across the contacting surfaces to establish good electrical continuity.
