Interlock system and method for rotary disconnect switches

A method of controlling a position of an enclosure, the method comprising:

• attaching a rotary handle on a door of the enclosure;
• disposing a disconnect switch in an interior of the enclosure, the disconnect switch including a shaft extending toward an exterior of the enclosure, the handle configured to engage the shaft when the door is in the closed position and rotate the shaft to move the shaft of the disconnect switch between an on position and an off position;
• attaching a first interlocking member to the door, the first interlocking member extending toward an interior of the enclosure;
• attaching a second interlocking member attached to the shaft;
• moving the shaft of the disconnect switch between the on position and the off position;
• responsive to the disconnect switch being in the on position, engaging the first interlocking member with the second interlocking member to i) prevent the door from being moved from the closed position toward the open position and ii) allow the door to be moved from the open position toward the closed position;
• and
• responsive to the disconnect switch being in the off position, engaging the first interlocking member with the second interlocking member to allow the door to be moved between the open position and the closed position, wherein the second interlocking member is a cantilever beam rotatably attached to the shaft and configured to rotate about an axis that is orthogonal to a rotational axis of the shaft.
