MSD service switch

The manual maintenance protection switch is a manual maintenance protection switch with high-voltage interlock function used for the high-voltage box or battery box of electric vehicles. It is mainly used for the protection and control of the internal main circuit of electric vehicles to prevent excessive current. When the main circuit current is disconnected. With the development of new energy vehicles, MSD (manual disconnection service) has also been widely used. The application fields of MSD connectors are mainly the maintenance switches of new energy vehicles and the short circuit protection of high-voltage circuit systems, as well as the power supply system, pdu, etc. Generally speaking, its role is to protect the safety of technicians in repairing electric vehicles in high-voltage environments, or to deal with certain emergencies. It allows quick separation of high-voltage circuit connections for safer maintenance and other work.

MSD seems to have become an indispensable part of electric vehicles, or a necessary disconnecting device for emergency rescue.
