In a switching device (S) for electrical installations with a housing ( 2 ) having terminals ( 1 ), it is proposed for increasing the safety margin against spark-over between electrically conducting outside sections of two adjacent, identically constructed switching elements to provide at least one shielding element ( 3 ) that is formed as one-piece on the housing in a region of the terminals ( 1 ), or at least one recess ( 8 ), indentation ( 8 ) and the like, for lengthening the leakage current path on at least one housing part and/or on at least one section formed on the housing ( 2 ). In addition, in a switching device (S) for an electrical installations having a housing ( 2 ), with at least one terminal ( 1 ), means are provided for completely unscrewing the clamping screw ( 15 ) from the clamping opening ( 17 ) for easy insertion of ring cable lugs.
