Abstract: A beverage dispensing gun includes a case housing a replaceable nozzle, which defines a number of liquid passageways, and a beverage selection button array. The liquid passageways are connected to flexible liquid lines. A printed circuit (PC) board, mounted within the case underlying the button array, includes pressure actuated switches actuated when the corresponding button is depressed. Holes in the rigid PC board beneath each button house light emitting diodes to light up the buttons to aid visibility. The PC board is protected from moisture using a flexible plastic film on the upper surface and a rubber boot covering the bottom and the peripheral edge of the PC board. A metal band sealingly secures the peripheral edge of the rubber boot to the PC board. The speed of the liquid is reduced as it passes through the nozzle by increasing the area of the passageway. This is achieved by either injecting the fluid into a common, enlarged passageway section or by enlarging each passageway with a venturi region.
