摘要： A mobile contact-holder for a cutout includes a support in which there is formed a housing, a mobile element made of electrically conductive material mounted to slide, in a longitudinal axis of the support, in the housing of the support, an upstream electrical contact pad and a downstream electrical contact pad borne by the mobile element and a spring which exerts a return force on the mobile element. The support includes two oblong holes emerging in the housing and extending along its longitudinal axis. The mobile contact-holder also includes a guiding shaft which is fixed in translation with respect to the mobile element, which extends along an axis parallel to a transverse axis of the support and which is engaged in the oblong holes of the support. The guiding shaft engaged in the oblong holes guides the translation of the mobile element in the housing.

摘要： 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 to quickly leave the contact point, enhance the mechanical strength of the stationary contact and reduce the production cost of the contact.

摘要： A removable electric current switching element includes first and second housing parts fitted to the other and that can be moved between an assembled configuration and a partially disassembled configuration. The first housing part includes side walls provided with through inspection windows, the second housing part includes insulating walls which each delimit a volume in the second housing part around a corresponding mobile conductor. The first and second housing parts are arranged relative to one another in such a way that, in the assembled configuration the insulating walls mask the inspection windows and that, in the intermediate configuration the insulating walls are away from the inspection windows to free access to the inspection windows.
