I have setup a magnetic door lock controlled by a sonoff sv and it works great. Now I need to add a latching switch to have the option to lock or unlock the door with the switch or the sonoff sv, almost like a 3-way switch but using 12v DC. I am new to sonoff products and not familiar with all the mods but I am sue this has been done before but I could not find any reference to this scenario. Any assistance would be appreciated.

I'm not sure if I've misunderstood your issue but are you saying the latching switch you want to use has a 12V output?
