    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.

    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: 2076000 9112616 PCTABS00006 An electrical device (1) in which a first connection element (7) is in electrical contact with a resistive element (3). The first connection element (7) defines a cavity (11) into which, when the cavity is empty, a second connection element (21) can be inserted. The second connection element (21), which may be connected to a source of electrical power, is partially within the cavity (11), makes physical and electrical contact with the first connection element (7), and protrudes from the cavity. Such devices (1) can be made in a continuous process by a method of the invention. They are particularly suitable for insertion into a circuit board (31).
