ABSTRACT:
Enclosed switching apparatus has a tank, a circuit breaker, a pair of contact pedestals provided on both sides of the circuit breaker, and a disconnecting switch. The tank is provided with a lead-out portion extending in a direction perpendicular to the axis of the breaker and disposed adjacent to one of the contact pedestal. The disconnecting switch is at least partially disposed in the lead-out portion, with the axis of the disconnecting switch being coincident with the axis of the lead-out portion. An operating device is provided for operation of the movable contact of the disconnecting switch. A drive bar member couples the movable contact to the operating device, extends through the tank along a line of extension of the axis of the disconnecting switch and includes a conductor portion electrically connected to the movable contact. A slide contact is mounted on the above-mentioned one of the contact pedestals to slidably receive the conductor portion of the drive bar member.
