The frog refers to the pointed crossing point of the two rails in the middle of a turnout. As this is common to both of the two tracks the power in this section of the track either needs to be switched when the turnout is changed or electrically insulated from the rest of the point. Electrofrog refers to when this section of track is live and the power needs to be switched, and insulfrog means this section of track is insulated.
