Abstract: 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.
