FIELD: electric engineering.
SUBSTANCE: force switch contains contact part moveable in axial direction and with flow moving in case of commutation in axial direction, which flow is coaxially enveloped by flow guiding device, which in side surface has at least one outlet aperture for deviation of at least part of arc-suppressing gas flow in direction of outlet, while direction of outlet is directed tangentially mainly perpendicularly to axial direction.
EFFECT: increased arc suppression efficiency due to optimized deflection of arc-suppressing gas flow.
