Abstract

A control mechanism for a switchgear equipment, includes a conductor located in a downward facing cantilever manner to form a stationary contact of a disconnector switch or a disconnector mechanism and a conductor in an upward facing manner to form a stationary contact of an earthing switch or an earthing mechanism, for obtaining the states of disconnection, neutral, and earthing. A cylindrical moving contact with an angularly displaceable shaft at its' operative distal end with angular displacement of the shaft being about its operative proximal pivot point, can be engaged with a slot of a slotted disc such that linear displacement of the cylindrical moving contact causes corresponding angular displacement of the shaft to achieve a disconnection state and further angular displacement of the engaged disc to achieve a neutral state.
