<p>An electrical coil module of planar type referably manufactured by means of printed circuit techniques on a generally flat substrate (21) has a first layout (20) of conducting material constituting a first electrical conductor having an input terminal (23), arranged on one side of said substrate (21). A second layout (20') of conducting material constituting a second electrical conductor having an output terminal (24), is arranged on the opposite side of said substrate. The first and second conductors are connected by means of an electrical connection (22) through the substrate (21), so that an electrical voltage connected between the input and output terminals of the coil module will drive a current from one terminal through the conductor on one side of the substrate via connection (22) through the substrate and the conductor on the other side of the substrate to the other terminal. An electrical coil comprising such modules is also described as well as an actuation mechanism including such a coil and an electrical circuit breaker comprising such an actuation mechanism.</p> |
