A switch including a housing, a first contact arrangement having a first commutation contact element and a first contact, a second contact arrangement having a second commutation contact element and a second contact, and also a nominal contact arrangement. The first commutation contact element and the second commutation contact element form a snap-action connection with one another in the closed position of the commutation contact element. When the switch is closed, a distance between the first contact and the second contact is smaller than a distance between the first commutation contact element and the second commutation contact element in the direction of the axis.

Switch and method for disconnecting a switch

A gas-insulated switchgear assembly having a first module and a second module, which each have a gas area, which is in the form of a pressure vessel, is filled with an insulating gas and has at least two phase conductors. The first module is connected to the second module such that the first gas area and the second gas area are hydraulically separated from one another by an insulating body, while the phase conductors in the first module are electrically connected to the phase conductors at the same electrical potential in the second module. The at least two phase conductors in the first module can be electrically connected to the at least two phase conductors at the same electrical potential in the second module, in each case via a detachable plug connection.
