UNIFROG EXPLAINED For current users of the Electrofrog or Insulfrog versions of our turnouts the new Unifrog format gives modellers the best of both worlds. As supplied, the turnout is wired completely "live", except for the frog tip and wing rails, and can be used straight out of the packet without any further modification (and so behaves like an Insulfrog). However, the modeller can choose to electrify the frog and wing rails by connecting the pre-welded wires as shown on the diagram below. To change polarity the modeller can use our PL-13 or PL-15 change-over switch/microswitch, or the SmartSwitch SmartFrog PLS-130.
