Abstract: Switch apparatus is disclosed. The switch apparatus has an enclosure, having a openable cover, a switch disposed within the enclosure, a handle in operative communication with the switch, a spring in biasing communication with the handle, and interlocking members. The interlocking members, the handle, the biasing spring and the switch having positions relative to each other such that the interlocking members lock the cover in a closed position in response to the handle being biased toward an OFF position, and the switch contacts being closed. Further disclosed is a method for unlocking a closed cover of a switch apparatus. A spring biased handle is changed to an OFF biased position from an ON biased position passing through a non-biased position. Subsequent thereto, a switch being changed from a closed circuit to an open circuit position. Subsequent thereto, interlocking members are changed from an interlocked to a non-interlocked position.
