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.

Abstract: The use for an electrical device (1) of an element (7) composed of a conductive polymer is positioned in contact with the surface layer of one or more metal electrodes (3, 5). The metal electrode contains a base layer (9) which comprises a first metal, an intermediate metal layer (15) which comprises a metal that is different from the first metal, and a surface layer (17) which (i) comprises a second metal, (ii) has a centre line average roughness Ra of at least 1.3, and (iii) has a reflection density Rd of at least 0.60. The conductive polymer composition preferably exhibits PTC behaviour. The electrical devices, which may be, for example, circuit protection devices or heaters, have improved thermal and electrical performance over devices compared with electrodes which do not meet the centre line average roughness and reflection density requirements.

Abstract: An electrical device in which a first connection element is in electrical contact with a resistive element. The first connection element defines a cavity into which, when the cavity is empty, a second connection element can be inserted. The second connection element, which may be connected to a source of electrical power, is partially within the cavity, makes physical and electrical contact with the first connection element, and protrudes from the cavity. Such devices can be made in a continuous process by a method of the invention. They are particularly suitable for insertion into a circuit board.
