  • Electrical devices
    Patent number: 6651315
    Abstract: An electrical device which comprises first and second laminar electrodes and a laminar PTC resistive element sandwiched between them, the device comprising: (a) a main portion which comprises a main part of the first electrode, a main part of the second electrode, and a main part of the resistive element; and (b) a first connection leg which extends away from the main portion and which comprises a first leg part of the first electrode which is integral with the main part of the first electrode, and a first leg part of the resistive element which is integral with the main part of the resistive element. Such devices can be secured to circuit boards in a variety of ways, and to elastically deformed terminals. Preferably preferred devices contain two laminar electrodes, with a PTC element between them, and a cross-conductor which passes through the thickness of the device and contacts one only of the two electrodes.
