摘要

Electrical device comprises a circuit board (2) and a dome switching mat (3) made from a permanent elastic material arranged between a housing lower part (1b) and a housing upper part (1a) of an insulating housing (1). The housing upper part is supported on the circuit board by projections (1a') provided on the housing upper part. Electrical device comprises a circuit board (2) and a dome switching mat (3) made from a permanent elastic material arranged between a housing lower part (1b) and a housing upper part (1a) of an insulating housing (1). The housing upper part is supported on the circuit board by projections (1a') provided on the housing upper part. A material layer made from a permanent elastic material is inserted between the upper and lower parts. The circuit board is tensioned on the edge side between the lower part and the upper part via a clip connection.
