Abstract

An electrical device includes two housing parts that may be joined to form one closed housing, the housing parts in the joined state enclosing a housing interior space, as well as an electrical/electronic circuit element arranged in the housing inner space, and a sealing material for protecting the circuit element. The two housing parts may be configured as half-shells and the interior area of the half-shells, in each case, may be subdivided by interior walls into at least two chambers, of which, in each case, a first chamber is filled with the sealing material and has spatial dimensions which are greater than the dimensions of the circuit element, the interior walls of the second half-shell, in the joined state of the two half-shells, overlapping the interior walls of the first half-shell with clearance, the interior walls of the first half-shell penetrating somewhat into the first chamber of the second half-shell, and the circuit element between the two half-shells being enveloped by the sealing material contained in the two first chambers, up to its electrical connections.
