ABSTRACT:
A disconnect means is provided which is particularly suited to be employed in connection with an electrically powered motor vehicle for purposes of effecting an emergency disconnect of the electrical power circuit thereof. The subject disconnect means includes a knife switch movable between a normally closed position and an open position, latching means operable to hold the knife switch in the normally closed position thereof, first and second terminal means, actuator means operable for causing the knife switch to move from the normally closed to the open condition thereof, reset means and enclosure means. The latching means includes a clevis suitably mounted on the second terminal means for movement between a latching condition wherein the clevis is in engagement with the knife switch and an unlatching condition wherein the clevis is disengaged from the knife switch. The actuator means is operatively connected to the clevis so as to be capable of causing the clevis to move between the latching and the unlatching conditions thereof. The reset means is operatively connected to the knife switch and is required to be employed for purposes of effecting the resetting of the knife switch, i.e., to cause the knife switch to move between the open position and the normally closed position thereof.
