A powered painting system includes a motor driven paint pump controlled by a radio signal receiver associated with it. A radio frequency transmitter mounts to the wrist of the painter, and a small clip with a button-operated switch thereon is provided for mounting to the finger of the painter, with the button readily accessible to the thumb of the painter. Upon operation of the button by the thumb, the transmitter sends a signal to the receiver which turns the pump on. Upon subsequent operation of the button, the transmitter sends a further signal which, upon receipt by the receiver, turns off the pump.
