ABSTRACT:
A wind-controlled spraying apparatus is arranged to contain electrical contacts and essential mechanical parts within a single housing and to provide switching contacts on a printed circuit board designed as part of a control circuit for the spraying apparatus. The apparatus includes a nozzle that sprays insecticides into the wind for predetermined periods of time in response to changes in wind direction indicated by a wind-blown conducting tube that contacts only one of the switching contacts on the printed circuit board at any time. An open-ended plastic skirt in the form of a truncated cone has inwardly projecting fingers arranged around the skirt end in contact with the bottom surface of the printed circuit board and extending beyond the edge of the hole in the printed circuit board, dimensioned to fit between the switch contacts thereon to prevent the swinging conducting tube from simultaneously striking more than one of the adjacent switch contacts on the printed circuit board and quickly shifting from one contact to the other in response to small changes in wind direction.
