<p>Laminar electrical devices, in particular circuit protection devices, contain two laminar electrodes (13,15), with a PTC element (17) between them, and a cross-conductor (51) which passes through the thickness of the device and contacts one only of the two electrodes. This permits connection to both electrodes from the same side of the device. The device also includes layers of solder (64,65,66,67) on the areas of the device through which connection is made, and separation and/or masking members (81,82,85) which (a) reduce the danger of short circuits formed by solder flow during installation of the device and/or (b) provide a site for permanent marking of the device. <IMAGE></p> |
