An apparatus includes an enclosure (e.g., an MCC bucket enclosure) having a cover configured to be opened, a disconnect switch positioned in the enclosure, and a shaft having a first end inserted in the disconnect switch and configured to actuate at least one switch in the disconnect switch by rotation of the shaft. The apparatus further includes a switch handle mechanism mounted on the cover, configured to receive a second end of the shaft when the cover is in a closed position, and comprising a switch handle configured to rotate the shaft. The switch handle mechanism may be configured to allow withdrawal of the second end of the shaft from the switch handle mechanism when the switch handle is in a first position to allow opening of the cover and to prevent withdrawal of the second end of the shaft from the switch handle mechanism wherein the switch handle is in a second position to prevent opening of the cover.
