Taz 6 dual extruder v3 Z switch adapter slips out of place

The Z stop adapter on my Taz 6 with a dual v3 extruder slips out of place once in a while. When it tries to home with the adapter out of place, it can’t push the Z toggle into the stop switch so it keeps mashing the nozzles into the toggle until you cut the power. Has anyone else experienced this? There are screw holes in the Z switch mount with recessed screws. I think a modified Z adapter with “pins” that slip into the screw holes would prevent the adapter from slipping out of place. Thoughts?
