Electrical safety system for motor vehicle, has mass connection device accommodating separating part of switch and setting battery loading circuit on mass potential in case of separation of circuit, where part is driven by propellant

摘要

The system has a pyrotechnic separator separating a battery loading circuit using an isolating switch in case of need of a main battery and a main power supply. A mass connection device (3) accommodates a separating part (5) of the switch and sets the circuit on mass potential in the case of separation of the circuit, where the part is driven by a propellant and is connected with the circuit in an electrically conducting manner.
