Patent ID: 8395062

Claim:
A switch comprising a conductive movable member and at least first and second terminals and being switchable by mechanically moving the movable member between a state in which the movable member contacts with the first and second terminals simultaneously and a state in which the movable member is apart from either one of the first and second terminals, wherein at least one of the first and second terminals comprises (i) a conductive contact part for contacting with the movable member, the conductive contact part being formed with edges functioning as a spacer; (ii) a conductive connect part for being electrically connected with an external element; and (iii) a PTC member located between the contact part and the connect part, said PTC member comprising a PTC element having a PTC material layer and a pair of conductive material layers each located on opposed surfaces of the PTC material layer, the pair of conductive material layers comprising metal foils being electrically connected with the contact part and the connect part, respectively.
