A switching installation for the power supply battery of an electrically driven mining vehicle consists of an interrupter (18) at or near the middle of the chain of cells (10) forming the battery and interlocked with plug and socket connectors (16, 17) at the terminals of the battery, so that the plugs cannot be withdrawn from the sockets without opening the interrupter and reducing the terminal potentials to zero. The switch may be operated in response to optical, electrical, mechanical, pneumatic or hydraulic sensing. <IMAGE> |
