  • Publication number: 20100163261
    Abstract: A power tool with a housing, a multi-speed transmission and a switch mechanism. The switch mechanism has an actuator, a rail, a switch and first and second springs. The actuator is movable along a longitudinal axis of the transmission between a plurality of positions and is engaged to one or more members of the transmission at each of the plurality of actuator positions such that the transmission operates in a corresponding one of a plurality of different overall speed reduction ratios. The actuator is non-rotatably but axially slidably engaged to the housing. The rail is fixedly coupled to the actuator and is received through the switch such that the switch is mounted on the rail for sliding movement thereon. The first spring is disposed between the actuator and the switch and biases the switch away from the actuator. The second spring is disposed between the switch and an end of the rail opposite the actuator and biases biasing the switch away from the end of the rail.
