ABSTRACT:
A fused disconnect switch is contained within a molded plastic cover pivotally attached to a molded plastic case. The switch contact blade is directly attached to the cover whereby movement of the cover in one direction slidingly connects the switch contact blade between the line and load stabs mounted within the case. Movement of the cover in an opposite direction slidingly disconnects the switch contact blade from the line and load stabs. Tabs integrally formed within the cover and slots integrally formed within the case cooperate to prevent access to the switch components when the switch blade is in its "ON" position. An opening is provided for locking the switch in either the "ON" or "OFF" position.
