ABSTRACT:
A power tool with a housing, a motor, an output spindle and a transmission assembly with a transmission and a speed selector. The transmission includes a plurality of planetary transmission stages that couple the motor to the output spindle. The speed selector includes only one switch member that is slidably movable between three positions to cause the transmission to operate in a corresponding number of speed ratios.
