switchgear singular

Morphology

switchgear = switch + gear (semi-transparent) = switch + gear

The compound literally combines 'switch' and 'gear', but the technical, specialized meaning (an assembly of switching and protective equipment) may not be fully obvious to general learners.

Etymology

Switchgear joins two simple words: switch meaning 'turn on or off' and gear meaning 'equipment', as in 'camping gear'. So, switchgear is the equipment that controls and protects electrical circuits.
