A motor driven paint mixer which is designed to prevent accidental and/or unintentional actuation is disclosed. The paint mixer comprises a two speed electric motor having a motor shaft, a detachable extension shaft mechanically coupled at one end to the motor shaft and having paint mixing elements at the other end thereof, a support assembly for supporting the electric motor on one side of a paint can, a power supply cord for connecting the electric motor to an electrical power source and a control box mechanically mounted on the electric motor and electrically interposed in the power supply cord connected to the electric motor. The control box includes a double throw double pole toggle switch having two on positions and a center off position and a relay. The relay and switch are connected in series and operate in a manner such that if there is a loss in power to the electric motor for any reason while the switch is in an on position the relay will open and remain open after the power has been restored until the switch is first returned to the off position and then moved to an on position. The toggle switch is mounted in a recessed portion of the control box to minimize the possibility of accidentally moving from the off position to an on position.
