Abstract
Embodiments of the present disclosure provide a stationary contact assembly and a corresponding switch contact. The stationary contact assembly comprises: a stationary contact body (21); a stationary contact point (23) placed on the stationary contact body (21); and an arc-guiding member (25) fixed on the stationary contact body (21) and including an arc guiding portion (251), the arc guiding portion (251) comprising a first end (A) and a second end (B) that are opposite to each other, the first end (A) being close to the stationary contact point (23), a direction form the first end (A) to the second end (B) defining a main movement direction (F) of arc. The arc guiding portion (251) of the arc-guiding member (25) comprises an arc-guiding section (2511) at the first end (A), the arc-guiding section is adapted to guide the arc away from the stationary contact point (23) into the arc guiding portion (251), and the stationary contact point (23) is close to or in contact with the arc-guiding section (2511) in the main movement direction (F) of the arc. The stationary contact assembly of the embodiments of the present disclosure has an improved arc-guiding member that can guide the arc …
