Abstract
A power tool such as a hand held vacuum cleaner, has a housing and nozzle. The housing mounts a motor and switch carrier. A battery pack powers the motor. The electrical arrangements comprise conductors punched from a single strip and fixed in guides formed on the carrier. Terminals of the motor and battery are pressed through slits in some conductors. The conductors pass into tracks formed on a tray of the switch. A mask is positioned on the tray to expose the conductors in discrete switch positions of slide connectors mounted in a switch slide slidably mounted on the tray. A mask (78) is positioned on the tray to expose the conductors in discrete switch positions (A, B, C) of slide connectors (68) mounted in a switch slide (64) slidably mounted on the tray.
