The W key selector box is designed to enable the controlled release of keys by the positioning of a selector knob. It is typically used in switchgear applications ensuring multiple supplies are not applied to common bus bars. The W box is suitable for releasing any number of keys, in a pre-determined sequence in differing combinations. A maximum of six selector knob positions is available. The requirement for this type of product usually arises due to various system setups i.e. in the control of switchgear. The W box is supplied in an enclosure suitable for surface mounting.
