A reversing switch and more particularly a diaphragm operated electrical polarity reversing switch which has general utility but in the application the reversing switch is disclosed for use in combination with a vehicle mounted spray device including a discharge nozzle which may be used for applying chemicals, liquid fertilizers and other liquids such as when applying such materials alongside of roadways to effectively apply liquid throughout the width of the road right-of-way in which spray nozzles are, mounted adjustably on a pivotal arm-type support assembly at the right front of a vehicle and a control arrangement is oriented in the cab of the vehicle to enable the vehicle operator to control the spray apparatus. A diaphragm is communicated with a pressurized supply line with the diaphragm being responsive to pressure in the supply line together with a control valve to direct flow to one of a plurality of different sized nozzles in order to maintain a constant pressure of liquid at each nozzle with any temporary variation in the pressure caused by switching from one nozzle to another being promptly corrected thus providing a constant flow rate and constant width of discharge of liquid from the nozzle.
