ABSTRACT:
An electrical connection device includes a substrate, first and second semiconductor patterns formed on the substrate, and a contact having two contact terminals. The first semiconductor pattern has a first OFF pattern section. The second semiconductor pattern has at least two second OFF pattern sections. The two contact terminals are at different voltage levels and are disposed to touch the first semiconductor pattern and/or the second semiconductor pattern, selectively causing electricity to flow through the semiconductor patterns. No electricity flows if both the contact terminals touch either the first OFF pattern section or one of the second OFF pattern sections. The arrangement of the first OFF pattern section and the second OFF pattern sections preserves the functionality of the electrical connection device, yet reduces its size.
