FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, namely to power supply sources and power distribution. Switch comprises a control system, a first manipulation mechanism and a second manipulation mechanism. Control system issues an operating instruction to the second manipulation mechanism when the assembly is serviceable. Operating instruction is configured to issue a command to the second manipulation mechanism to perform an opening operation or a closing operation. Control system issues a first instruction to perform an operation to the first manipulation mechanism and a second instruction to perform an operation to the second manipulation mechanism, respectively, in case of wiring failure. First operation execution instruction is configured to issue a first operation instruction to the first manipulation mechanism, and the second instruction to perform the operation is configured to issue a second manipulation instruction to the second manipulation mechanism. Combined action of the first manipulation mechanism and the second manipulation mechanism realizes redundancy of the switch. Time spent by the first manipulation mechanism performing the first operation differs from the time spent by the second manipulation mechanism performing the second operation.
EFFECT: improvement of disconnection ability and increase of service life of switch and increase of system safety.
