I'm not quite sure that I'm interpreting the above correctly. But, the Smartswitch can be used with both Y leads and operate several control rods, from each Servo. Using the spare Servo arms, which come with each Servo, it's simple to use a spare arm to:-It would be far simpler to employ the switch pilot servo version and also extension for this, but also much more expensive in comparison to a simple Y lead and micro-switch/servo control rod.
Reduce the Servo throw from 180deg at the Servo, to the 3mm throw for the points and another rod, lower down the same servo arm, to the Peco Dual micro-switch, for Frog polarity.
The second micro-switch can isolate a length of track leading to the heel of the associated points, for heel protection.
It also has outputs for signals, at the right voltage for direct connection to LED signals.
