Thanks for the advice on how to wire switches folks though completely irrelevant to OP, he is using servo position events for Turnout feedback, no switches involved.
MERG CBUS servo modules can send an event when the servo
- Starts its move - To make Turnout inconsistent
- Midway position - Can be used to trigger switching frog power
- End point reached - Turnout closed / thrown
An issue with JMRI Layout Editor logic which deals with supporting Turnout feedback ( for any hardware type ) has been confirmed with a fix uploaded.
No more posts about switches required thanks,
Steve.
