A deactivation device for disconnecting an electrical energy source from a load includes at least two one-time switches. The one-time switches become inoperative upon switching in response to the presence of a load exceeding a critical value, thereby disconnecting an electrical connection. The one time switches are connected in parallel, and the deactivation device is configured in such a way that, except for a one-time switch, which is provided for disconnecting the energy source from the load and for connecting the energy source to the load, the at least one other one-time switch remains open. In the case of an inoperativeness of the one one-time switch, the at least one other one-time switch is used for disconnecting the energy source from the load and for connecting the energy source to the load.

1. A deactivation device for disconnecting an electrical energy source from a load, comprising: at least two one-time switches, the one-time switches becoming inoperative upon switching in response to presence of a load exceeding a critical value thereby disconnecting an electrical connection, the one-time switches being connected in parallel, and the deactivation device being configured in such a way that one of the one-time switches is for disconnecting the energy source from the load and for connecting the energy source to the load, and the at least one other one-time switch remains open, except in a case of an inoperativeness of the one of the one-time switches, in which case the at least one other one-time switch is used for disconnecting the energy source from the load and for connecting the energy source to the load. 2. The deactivation device as recited in claim 1, wherein the one-time switches include at least one of a combustible relay and a combustible relay device having a series connected relay and an explosive protection device that is ignitable when critical value load is exceeded. 3. A circuit system, comprising: an electrical energy source;a load; anda deactivation device connected between the energy source and the load to disconnect the load from the energy source and to connect the load to the energy source, the deactivation device including at least two one-time switches, the one-time switches becoming inoperative upon switching in response to presence of a load exceeding a critical value, thereby disconnecting an electrical connection, the one-time switches being connected in parallel, and the deactivation device being configured in such a way that one of the one-time switches is provided for disconnecting the energy source from the load and for connecting the energy source to the load, and the at least one other one-time switch remains open, except in a case of an inoperativeness of the one of the one-time switches, in which case the at least one other one-time switch is used for disconnecting the energy source from the load and for connecting the energy source to the load. 4. The circuit system as recited in claim 3, wherein the energy source is a battery. 5. A circuit system, comprising: an electrical energy source;a load; anda deactivation device connected between the energy source and the load to disconnect the load from the energy source and to connect the load to the energy source, the deactivation device including at least two one-time switches, the one-time switches becoming inoperative upon switching in response to presence of a load exceeding a critical value, thereby disconnecting an electrical connection, the one-time switches being connected in parallel, and the deactivation device being configured in such a way that one of the one-time switches is provided for disconnecting the energy source from the load and for connecting the energy source to the load, and the at least one other one-time switch remains open, except in a case of an inoperativeness of the one of the one-time switches, in which case the at least one other one-time switch is used for disconnecting the energy source from the load and for connecting the energy source to the load,wherein the deactivation device is connected between a terminal of the energy source and the load, and a further switch is connected between another terminal of the energy source and the load. 6. The circuit system as recited in claim 5, wherein at least one of the one-time switches is initially opened to disconnect the load from the energy source, and the further switch is subsequently opened. 7. The circuit system as recited in claim 5, the further switch is a one-time switch of a further deactivation system that is connected between the energy source and the load.
