<p>The invention relates to a high voltage replacement element for passenger cars, meant for protecting the heating installation circuits against short-circuits. According to the invention, the high voltage replacement element shows fusible elements made of more silver strips (1a) which are very thin and of a relatively small length, having, from place to place, practiced section contractions, by cutting out some metal portions as circle segments, symmetrical in relation to the strip longitudinal symmetry axis. The fusible elements are parallelly connected by pasting the ends on some terminals (13), which will be pasted on the caps (2c and 3c) of the replacement elements, which may have knife-type or cylindrical contacts and to which the pipes (2b) for fastening the knife-type contacts and the cylindrical contacts (3b) are assembled by puttying or by means of a device for distorting metals, based on the electromagnetic effect.</p> |
