The basin is configured to guide debris entering the basin toward the channel and the channel is configured to channel debris to the outlet. ## Claims ### Claim 1 An assembly for receiving debris into a suction debris collection system, the assembly comprising: a receptacle; a drawer slideable in the receptacle between a single closed position and an open position, an exterior perimeter shape of the drawer conforming to an interior perimeter shape of the receptacle and the drawer including a floor and walls extending up from the floor, the floor and the walls defining a chamber through which air may pass to a suction port at a rear part of the receptacle when the drawer is in an open position and suction is supplied to the port; a seal integral with the drawer and configured to seal the suction port when the drawer is in the closed position; and an electrical switch operable between an off position when the drawer is in the closed position and an on position when the drawer is in an open position. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the receptacle covers the chamber when the drawer is in the closed position and the assembly further comprises a base plate attached to the receptacle along the floor of the drawer such that the drawer is substantially enclosed within the receptacle and the base plate when the drawer is in the closed position. ### Claim 3 (depends on 2) The assembly of claim 2, wherein the receptacle comprises a tray conforming substantially to a shape of the drawer. ### Claim 4 (depends on 2) The assembly of claim 2, wherein the base plate has an opening therein to the suction port, the opening located at a rear part of the base plate, and the seal comprises a seal configured to seal the opening in the base plate when the drawer is in the closed position. ### Claim 5 (depends on 1) The assembly of claim 1, further comprising a cover attached to the receptacle such that the chamber is fully covered by the cover when the drawer is in the closed position and the chamber is only partially covered by the cover when the drawer is in an open position. ### Claim 6 (depends on 5) The assembly of claim 5, wherein the receptacle comprises a tray conforming substantially to a shape of the drawer. ### Claim 7 (depends on 5) The assembly of claim 5, wherein the receptacle has an opening therein to the suction port, the opening located at a rear part of the receptacle, and the seal comprises a seal configured to seal the opening in the receptacle when the drawer is in the closed position. ### Claim 8 (depends on 1) The assembly of claim 1, wherein the switch comprises a rocker switch mounted to the receptacle such that moving the drawer from the closed position to an open position rocks the switch to the on position and moving the drawer from an open position to the closed position rocks the switch to the off position. ### Claim 9 (depends on 1) The assembly of claim 1, wherein the drawer is open across a front of the chamber. ### Claim 10 (depends on 9) The assembly of claim 9, wherein the drawer further includes a push block located along the front of the chamber. ### Claim 11 (depends on 1) The assembly of claim 1, wherein the drawer further includes a front end wall extending across a front of the chamber between forward ends of the sidewalls. ### Claim 12 (depends on 1) The assembly of claim 1, further comprising a releasable catch operatively connected between the receptacle and the drawer for holding the drawer in the closed position until the catch is released. ### Claim 13 (depends on 1) The assembly of claim 1, further comprising a biasing mechanism operatively connected between the receptacle and the drawer, the biasing mechanism configured to bias the drawer toward an open position. ### Claim 14 An assembly for receiving debris into a suction debris collection system, the assembly comprising: a receptacle; a drawer slideable in a receptacle bay between a single closed position and an open position, an exterior perimeter shape of the drawer conforming to an interior perimeter shape of the receptacle, the drawer including a basin and a channel from the basin through which air may pass to a suction port at a rear part of the receptacle when the drawer is in an open position and suction is supplied to the port; a seal integral with the drawer and configured to seal the suction port when the drawer is in the closed position; and an electrical switch operable between an off position when the drawer is in the closed position and an on position when the drawer is in an open position. ### Claim 15 (depends on 14) The assembly of claim 14, further comprising an outlet from the channel to the suction port and wherein the channel extends from a more narrow part of the channel at the basin to a more broad part of the channel at the outlet. ### Claim 16 (depends on 15) The assembly of claim 15, wherein the channel includes: a tapered section in which the channel tapers from the more narrow part of the channel at the basin to the more broad part of the channel; and a straight section extending along the more broad part of the channel to the outlet. ### Claim 17 An assembly for receiving debris into a suction debris collection system, the assembly comprising: a receptacle characterized by a floor, a ceiling, and walls extending between the floor and the ceiling, the floor, the ceiling, and the walls defining a bay and the receptacle having an opening therein at a rear part of the bay; a drawer slideable in the receptacle bay between a single closed position and an open position, the drawer comprising a generally Y-shaped chamber forming a basin at a more broad forward part of the chamber along the legs of the Y and forming a channel from the basin at a more narrow rearward part of the chamber along the stem of the Y; and a seal integral with the drawer and configured to seal the opening when the drawer is in the closed position. ### Claim 18 (depends on 17) The assembly of claim 17, further comprising an outlet from the channel and wherein the channel extends from a more narrow part of the channel at the basin to a more broad part of the channel at the outlet. ### Claim 19 (depends on 17) The assembly of claim 17, further comprising an electrical switch mounted to the receptacle such that moving the drawer from the closed position to an open position turns on the switch and moving the drawer from an open position to the closed position turns off the switch. ### Claim 20 (depends on 17) The assembly of claim 17, further comprising an electrical rocker switch mounted to the receptacle such that moving the drawer from the closed position to an open position rocks the switch to the on position and moving the drawer from an open position to the closed position rocks the switch to the off position.
