  • apparatus 100 includes an electrical circuit 624 between a source of power and electrical conductor elements 588.
  • the source of power may be an energy storage member 580 (e.g. battery) or a power cord 628 (connectable to an external power outlet), for example.
  • electrical conductor elements 588 may be de-energized when not connected with a mating electrical coupling (e.g. of a power accessory). This may prevent user injury from being hurt by inadvertent contact with the electrical conductor elements 588.
  • the electrical circuit 624 may include two or more electrical conductor elements 588, at least one of which, and preferably two of which, may be movable between a circuit closed position and a circuit open position, and biased to the circuit open position.
  • the electrical conductor element 588 In the circuit closed position, the electrical conductor element 588 is electrically connected to the source of power.
  • the electrical conductor 588 In the circuit open position, the electrical conductor 588 is electrically disconnected from the source of power. Accordingly, at least one of the electrical conductor elements 588 is normally electrically disconnected from the source of power, which may prevent accidental electric shock.
  • the electrical conductor element 588 is moved to the circuit closed position upon attaching an accessory tool to dirty air inlet 1 16.
  • the electrical conductor elements 588 may be moved to the circuit closed position by engagement with the electrical conductor elements of an accessory tool. Accordingly, when the accessory tool is mounted on inlet 1 16, the electrical conductor elements of the accessory tool may drive electrical conductor elements 588 to the circuit closed position.
  • electrical conductor elements 588 may be a rigid rod movably mounted in a housing 596 of electrical outlet 144. Each electrical conductor element 588 extends from a first contact end 640 to a second contact end 644.
  • the first contact end 640 may be an accessory tool contact end which makes electrical contact with a mating electrical conductor element of an attached accessory tool.
  • the second contact ends 644 may be a terminal end contact end which makes electrical contact with the terminal ends 636 of electrical conductive members 590 when the electrical conductor elements 588 are in a circuit closed position. Accordingly, when an accessory tool is electrically connected to electrical outlet 144 and electrical conductor elements 588 are in the circuit closed position, the conductor element 588 can conduct electricity from the source of power to the connected accessory tool.
  • electrical conductive members (e.g. wires) 590 extend from the source of power to terminal ends 636.
  • One or both of electrical conductor elements 588 may be movable between a circuit closed position, in which second contact end 644 contacts terminal end 636 of an electrical conductive member 590, and a circuit open position, in which second contact end 644 is spaced apart from the terminal ends 636 of electrical conductive members 590.
  • one or both of electrical conductor elements 588 may be axially slidable in electrical outlet housing between the circuit open and circuit closed positions.
  • electrical conductor elements 588 are rearwardly slideable in rearwardly extending housing channels 604 formed in electrical outlet housing 596.
  • first end 640 of one or both of electrical conductor elements 588 may be recessed into the electrical outlet 144 when in the circuit open position.
  • first end 640 may be positioned rearwardly of electrical outlet front end 608.
  • Electrical conductor element 588 may be biased to the circuit open position in any manner.
  • electrical outlet 144 includes a biasing member 648 that applies a biasing force urging electrical conductor element 588 toward the circuit open position.
  • biasing member 648 is a compression spring positioned between the electrical conductor element 588 and the terminal end 636 of electrical conductive member 590 which urges electrical conductor element 588 forwardly. The force of biasing member 648 may be overcome when connecting an accessory tool to dirty air inlet 1 6 to move the electrical conductor element 588 rearwardly to the circuit closed position.
  • biasing member 648 is substantially non-electrically conductive.
  • biasing member 648 may be formed of (or coated with) plastic, rubber, a non-conductive metal or another substantially non-electrically conductive material. This helps to prevent biasing member 648 from short circuiting electrical circuit 624 or electrically connecting electrical conductor element 588 and terminal end 632 when the electrical conductor element 588 is in the closed position.
  • electrical conductor elements 588 may be mounted in a moveable (e.g., plastic or other non-conductive material) housing and the housing may have an engagement member that is engaged by, e.g., a protrusion or finger provided on the accessory tool. In this way, the electrical conductor elements of the accessory tool need not be used to drive the circuit 624 to a closed position.
  • main power switch 650 which is movable between a circuit closed position and a circuit open position to energize the suction motor, may be part of electrical circuit 624.
  • the power switch may be manually user. In the circuit open position, power switch 650 electrically disconnects electrical terminal end 636 from the power source. In the circuit closed position, power switch 650 electrically connects circuit terminal end 636 with the power source.
