A double sided primed circuit board is shown wherein one side is etched for receiving a plurality of surface mounted components constituting a control circuit. In one embodiment the control circuit provides for regulating the operation of a plurality to the beverage dispensing valves. An op-amp monitors the conductor for sensing the operation of the beverage dispensing valves as a function of a voltage drop there across. The conductor operates as a resistor, and any heating thereof that occurs as a result of the operation of the beverage dispensing valve...
An electronic control circuit for sensing the operation of an electrically operated device, comprising: a double sided printed circuit board having an electronic control circuit means on a first surface thereof, and a resistance means comprising a plated conductor extending in a meandering pattern over a second surface of the circuit board from a first conductor end to a second conductor end thereof, and the plated conductor electrically connected to each of one or more first electrically operable devices, and the control circuit means including electric...
