Disconnector and earthing switch with telescopic contact

Abstract

A device having one or more switching mechanisms configured to disconnect a power supply from a load; and one or more disconnector and earthing switches, each disconnector and earthing switch associated with a respective switching mechanism. Each disconnector and earthing switch comprising a telescopic disconnector blade, wherein the disconnector blade is configured to pivot around a first end between three different positions. The three positions comprise: a first position in which the disconnector and earthing switch is closed and the power supply is connected to the load through the disconnector blade; a second, isolation, position in which the disconnector and earthing switch is open and the power supply is disconnected from the load; and a third position in which the power supply is disconnected from the load and a second end of the disconnector blade is electrically connected to an earthing contact.
