      We are using a different configuration for on/off switches: the switch
      is between the signal and +5V, and there is a pull-down resistor
      between the signal and the ground. Of course in this case we don't
      enable the pull-up resistor by software. Are there any disadvantages
      in using the pull-down configuration?
