PROTECTIVE COVER ARRANGEMENT ABSTRACT: Motorized high voltage switch operating mechanisms may have local control switches located on the front thereof which may be operated to control the opera- tion of the switch mechanism. It is desirable to limit access to the local control switches by a cover that may be locked to prevent unauthorized tampering or actuation. A cover is provided that is pivotable on a hinge to cover the switches. The cover is arranged so that it may be opened in two ways. First, when a lock is removed, the cover may be first moved upwardly to disengage a flange mounted on a door of the switch operating mechanism so that the cover can be pivoted to an open position. Second, even when the lock is in place, the door can be opened so that the flange disengages the cover so that the cover can be pivoted to an open position. The remote control blocking switch may be mounted beneath the cover so that when the cover is opened, remote operation of the switch operating mechanism is blocked.
