Inputs are working outside of trigger box until first overlap

I trying to make VR switch blueprint, similar to [interaction tutorial][1], but with the ability to switch lights with triggers of motion controllers. All works great with one exception. I can switch lights off and on even outside of the trigger volume, until first pawn and trigger overlap event. After that, all works correctly. Maybe I’m missing something in blueprints logic?
First two screens are switch blueprint, and the last on a trigger box, which toggles “pointer” from vr hand model
