In　addressing　the　issue　of　asynchronous　closing　during　the　closing　process　of　multi-break　electromagnetic　switches,　the　mechanism　of　electromagnetic　system　inter-coupling　was　analyzed,　and　a　coordinated　closing　control　strategy　for　multi-break　electromagnetic　switches　was　proposed.　By　using　a　laser　displacement　sensor　to　collect　contact　displacement　signals,　the　contact　displacement　signal　of　a　single-pole　switch　is　used　as　a　reference　displacement.　Other　switches　follow　this　reference　online,　achieving　synchronous　control　of　contact　displacements　and　thereby　synchronizing　the　moment　of　closure.　The　GD32F103　microcontroller　serves　as　the　control　core,　combined　with　a　dual　closed-loop　control　strategy　of　displacement　and　current　to　set　up　the　experimental　platform.　Experimental　results　show　that　the　coordinated　closing　control　strategy　effectively　enhances　the　synchronicity　of　the　closing　moment.　©　Beijing　Paike　Culture　Commu.　Co.,　Ltd.　2025.
