A movable handle and a power tool. The power tool comprises a housing, a motor supported by the housing and operable to drive a tool element about an axis, and a handle supported by the housing for rotation relative to the housing about the axis. Preferably, the power tool is a circular saw. The circular saw further comprises a switch assembly supported on the handle for movement with the handle and means for connecting the switch to the motor to accommodate movement of the switch relative to the motor. The switch assembly is electrically connectable to the motor and selectively connects the motor to a power source, and the connecting means includes a wiring arrangement. The circular saw further comprises a locking assembly for locking the handle in a position relative to the housing. Also, the circular saw preferably comprises means for preventing the switch assembly from connecting the motor to the power source when the locking assembly is in the unlocked condition and means for preventing the locking assembly from being operated from the locked condition to the unlocked condition when the switch assembly is in the operated condition.
