<p>The present invention relates to a powered painting system which includes a motor driven paint pump (28) controlled by a radio signal receiver (134) associated with it to supply paint to an applicator (133) held by a painter (27). In order to control operation of the pump (28) a radio frequency transmitter (32) mounts to the wrist of the painter (27), and a small clip (22,37) with a button-operated switch (24,41) thereon is provided for mounting to the finger of the painter (27), with the button readily accessible to the thumb of the painter. Upon operation of the button (24) by the thumb, the transmitter (11) sends a signal to the receiver (134) which turns the pump (28) on. Upon subsequent operation of the button (24), the transmitter (11) sends a further signal which, upon receipt by the receiver (134), turns off the pump (28).</p> |
