Abstract
An example electrical interruption switch includes a casing, surrounding a contact unit defining current path therethrough. The contact unit has a first and second connection contact and a separation region. A current supplied to the contact unit via the first connection contact can be discharged therefrom via the second connection contact, or vice versa. The separation region includes a tubular element, an axial direction of which runs along an axis X, wherein the tubular element is separable into two parts along a plane perpendicular to the axis X, whereby the current is interrupted between the first and the second connection contact, wherein the tubular element has two opposite end regions along the direction of extent of the axis X, characterized in that the tubular element has a minimum wall thickness, which increases in each case in the direction of the end regions, in a region between the end regions.
