    I’m not really sure why to be honest – My EM layout ‘Saltport’ uses DPDT switches at the baseboard edge, operating the points with wire-in-tube. Obviously I am only using one side of the DPDT so I’m not sure why I bought them!

    Having said that there are one or two complicated bits where both sides of the switch have been used, to energise the crossings on a crossover adjacent to the point in question, which obviates the need for a separate switch, so I suppose it has come in handy. Where the DPDT comes into its own would be with hacked servos, where one side would change the polarity and the other operate the servo.
