FIELD: process engineering.
SUBSTANCE: switching module has, at least, comprises, at least, one switch 2A composed of power semiconductor device, cooling appliance 3A of electrically conducting material and current feed appliance 1A abutting switch 2A whereon abuts switch 2A to cool switch 2A. Insulation means 8A is arranged between cooler 3A and current feeder 1A to isolate cooler 3A from current feeder 1A. Switch 2A, cooler 3A, current feeder 1A and insulator 8A are configured to arranged cooler at no potential which allows decreasing length of coolant feed pipes.
EFFECT: compact design.
