Embodiment Construction

[0039]1 and 2 show two switches S according to the invention with a housing 2, in particular a protective switch, wherein at least one terminal 1 is arranged in a recess 36 formed in the housing 2, in this case, The recess 36 is closed at least partially on the front side by a cover 30 , at least one plate-shaped or rib-shaped shielding element 3 protruding beyond the front cover 30 being integrally formed on the housing 2 .

[0040] In the use of the switch S the invention is not limited to the provision of only one disconnection gap, but rather in the use of the switch S a number of, in particular two or four disconnection gaps is provided.

[0041] The switch according to the invention has a housing 2 which is made of insulating material. The housing has a base body with a housing outer side 32 which, in a preferred arrangement of the switch according to the invention, is provided on a mounting rail as a contact surface with an adjacent, identical or different construction ...

Abstract

The invention relates to a switch (S) for an electrical installation, in particular a protective switch, which switch has a housing (2) containing terminals (1). In order to increase the safety against spark discharges between the conductive outsides of two adjacent switches, it is recommended to provide at least one shielding element (3) integrally formed on the housing in the area of ​​the terminal posts (1) or at least one Recesses (8) etc. are provided on the housing part and / or on at least one part formed on the housing (2) in order to extend the leakage distance. Furthermore, the invention relates to a switch for an electrical device, said switch having a housing (2) containing at least one cable terminal (1), the switch being provided with means for completely unscrewing a terminal screw from a terminal hole (17) (15) to simplify the introduction of ring cable terminals.

Description

technical field [0001] The invention relates to a switch with a housing, in particular a protective switch, in which at least one terminal pin is arranged in a recess formed in the switch housing, the recess then passing over at least a partial area of ​​the front side through a The lid is closed. Background technique [0002] Switches of this type are used in various applications as protective switches, especially line protection. [0003] Electric switches must comply with safety regulations. The close-packed application of electric switches in distribution boxes requires special safety signs for such switches. [0004] For example, the US-American UL 489 regulation specifies the minimum distance between live conductors of adjacent electrical switches that are accessible from the outside. For switches with operating voltage UN less than or equal to 300V, the air gap between two adjacent live conductors is required to be at least 19.1mm. When the operating voltage UN>...
