Electrical contact method

An electrical contact method, said method comprising:

• providing an axle having an axis of rotation;
• providing a plurality of cantilever arms, each cantilever arm of said plurality of cantilever arms having a first end and a second opposing end, said first end connected to said axle, said each cantilever arm extending radially outward from said axle about perpendicular to said axis of rotation;
• providing a plurality of electrically conductive contacts, wherein at least one electrically conductive contact of said plurality of electrically conductive contacts is disposed on said second end of each cantilever arm of said plurality of cantilever arms;
• supporting a sample on a support member;
• pressing said plurality of electrically conductive contacts against a first surface of said sample;
• and
• after said pressing, revolving said plurality of electrically conductive contacts about said axis of rotation, wherein said at least one electrically conductive contact of said plurality of electrically conductive contacts remains in electrical contact with said first surface.
