1. A switching device comprising: a housing comprising a latching protrusion, a base and a switching device cover coupled to said base;a line side terminal positioned on a line side of said housing;a load side terminal positioned on a load side of said housing, wherein the line side is opposite the load side;a first terminal cover coupled to said switching device cover proximate the line side;a second terminal cover coupled to said switching device cover proximate the load side, wherein said first terminal cover is movable between a closed position and an open position, wherein said first terminal cover covers said line side terminal in the closed position and provides access to said line side terminal in the open position, wherein said first terminal cover is attached to said switching device cover in both the closed and open positions, wherein said second terminal cover is moveable between a closed position and an open position, wherein said second terminal cover covers said load side terminal in the closed position and provides access to said load side terminal in the open position, and wherein said second terminal cover is attached to said switching device cover in both the closed and open positions;a first latching system that selectively latches said first terminal cover in the closed position and the open position, wherein said latching protrusion positively latches said first terminal cover in the open position; anda handle extending through a handle slot formed in said switching device cover, said handle disposed between said first and second terminal covers and operable to switch said switching device. 2. The switching device of claim 1, further comprising a second latching system that selectively latches said second terminal cover in the closed position and the open position. 3. The switching device of claim 1, wherein said first and second terminal covers are slidably attached to said switching device cover. 4. The switching device of claim 1, wherein said first and second terminal covers are pivotally coupled to said switching device cover. 5. The switching device of claim 4, wherein said first terminal cover comprises two fingers and a cover panel extending between said two fingers, wherein said two fingers are pivotally coupled to said switching device cover. 6. The switching device of claim 4, wherein said first terminal cover comprises a longitudinal side and a hinge extending along at least a portion of said longitudinal side, said hinge comprising a pin that rotatably engages said switching device cover. 7. The switching device of claim 4, wherein said first terminal cover comprises a hinged end and a free end, and, in the closed position of said first terminal cover, said hinged end is disposed between said free end and said handle. 8. A circuit breaker comprising: a housing comprising a switching device cover and a latching protrusion, said housing having a line side and a load side;a terminal cover assembly comprising a first terminal cover coupled to said switching device cover proximate one of the line side and the load side of said housing, wherein said first terminal cover is movable between an open position and a closed position, wherein said first terminal cover covers terminals at one of the line side and the load side in the closed position, wherein said first terminal cover provides access to the terminals in the open position, and wherein said first terminal cover is attached to said switching device cover in both the open and closed positions;a latching system that selectively latches said first terminal cover in the open position and in the closed position, wherein said latching protrusion positively latches said first terminal cover in the open position; anda handle extending through a handle slot formed in said switching device cover, said handle disposed between the line side and the load side and operable to switch said circuit breaker. 9. The circuit breaker of claim 8, wherein said latching system comprises said latching protrusion and a latching recess, wherein said latching protrusion is disposed in said latching recess when said first terminal cover is in the closed position, and wherein said latching protrusion is disposed outside of said latching recess when said first terminal cover is in the open position. 10. The circuit breaker of claim 8, wherein said first terminal cover comprises a reflective surface. 11. The circuit breaker of claim 8, wherein said latching system comprises a latching cam, first and second detents, and said latching protrusion, wherein said latching cam is disposed between said first and second detents on said first terminal cover. 12. The circuit breaker of claim 11, wherein said latching protrusion is disposed within said first detent when said first terminal cover is in the closed position, and wherein said latching protrusion is disposed within said second detent when said first terminal cover is in the open position. 13. The circuit breaker of claim 8, wherein said terminal cover assembly further comprises a second terminal cover coupled to said switching device cover proximate the other of the line side and the load side of said housing, said second terminal cover moveable between an open position and a closed position. 14. The circuit breaker of claim 13, wherein said first terminal cover is movable in a first direction from the closed position to the open position, wherein said second terminal cover is moveable in a second direction from the closed position to the open position, and wherein the first direction is opposite to the second direction. 15. The circuit breaker of claim 8, wherein said first terminal cover is pivotally coupled to said switching device cover. 16. The circuit breaker of claim 15, wherein said first terminal cover comprises two fingers and a cover panel extending between said two fingers, wherein said two fingers are pivotally coupled to said switching device cover. 17. The circuit breaker of claim 15, wherein said first terminal cover comprises a longitudinal side and a hinge extending along at least a portion of said longitudinal side, said hinge comprising a pin that rotatably engages said switching device cover. 18. The circuit breaker of claim 15, wherein said first terminal cover comprises a hinged end and a free end, and, in the closed position of said first terminal cover, said hinged end is disposed between said free end and said handle. 19. A method of selectively covering and accessing a terminal in a switching device, the switching device including a housing and a switching device cover coupled to the housing, the housing including a latching protrusion, the method comprising: coupling a first terminal cover to the switching device cover;coupling a handle to the switching device cover, the handle extending through a handle slot formed in the switching device cover, said handle disposed between a line side and a load side of the housing and operable to switch the switching device;placing the first terminal cover in a closed position to cover the terminal;moving the first terminal cover from the closed position to an open position to access the terminal, wherein the first terminal cover is attached to the switching device cover in both the closed and open positions; andlatching the first terminal cover to the housing in the open position, wherein the latching protrusion of the housing positively latches the first terminal cover in the open position. 20. The method of claim 19, wherein moving the first terminal cover from the closed position to an open position comprises pivoting the first terminal cover with respect to the housing. 21. The method of claim 19, wherein moving the first terminal cover from the closed position to an open position comprises sliding the first terminal cover with respect to the housing. 22. The method of claim 19, wherein placing the first terminal cover in a closed position comprises latching the first terminal cover to the housing in the closed position. 23. The method of claim 19, further comprising reflecting light onto the terminal using a reflective surface on the first terminal cover. 24. The method of claim 19, further comprising knocking out a knockout portion formed in the first terminal cover.
