Abstract
The electric device has a printed circuit board (10) which carries an electronic circuit with electronic components (12). The circuit is provided with a plug connector strip (14) for making electrical contact. In addition to the housing cover (27) and housing base (32), additional plastic coverings (16, 23) which are tight against moisture are provided to protect the circuit against moisture in a reliable manner and cover the printed circuit board on the upper side (11) and the underside (22) in the manner of a hood. These plastic parts are connected with the printed circuit board so as to be tight against moisture. The housing cover (27) and housing base (30) need not carry out any sealing functions and serve exclusively to protect against mechanical damage and, under certain circumstances, for shielding.
