Abstract: The present disclosure relates to a withdrawable base module for a switch. The withdrawable base module comprises a base coupled to a busbar for electrically connected to the switch; a conversion assembly coupled to the base and comprising a drive mechanism, a first female contact and a carrying mechanism adapted to carry the switch; and an auxiliary assembly being slidable relative to the conversion assembly and comprising a first male contact electrically connected to the switch; wherein the drive mechanism is operable to drive the auxiliary assembly to cause the first male contact to move towards and contact the first female contact. The withdrawable base module according to embodiments of the present disclosure can provide a test circuit for the switch, and can achieve the rocking-in or rocking-out of the switch without additional human intervention after completion of the test.

Abstract: A switching device for LV electric installations is disclosed which can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly. The mobile contact assembly is adapted to reversibly move between a first contact position, in which the movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.
