FIELD: electrical engineering.
SUBSTANCE: invention relates to a power switch with at least one polar device, which contains a movable contact, a pivotally mounted double-arm lever for opening and closing the movable contact, switch-on energy accumulator, as well as a disc cam, which is connected to the switch-on energy accumulator and through a drive link to the first end of the lever, the second end of which is connected to the movable contact of the polar device, and at least one switch-off energy accumulator. The drive link is a pivotally mounted interrupter shaft which interacts with the disc cam and is connected to the first end of the double-arm lever through the switch-off energy accumulator.
EFFECT: simpler and more compact design.
