Abstract: A magnetic membrane switch includes two opposed sheets of material which are magnetized in such a way that they repel each other. At least one of these sheets is flexible. The sheets are supported so that there is a predetermined spacing between them. The opposed faces of the sheets are provided with a thin metallic pattern. Portions of the metallic pattern can be made to contact one another by pressing on localized sections of the flexible sheet. The resulting contact achieves a switching operation. By placing an alpha-numeric code on one of the sheets, the switch can be utilized as a keyboard.
