Abstract (en)
[origin: WO2018184727A1] The invention relates to a switch device with at least one contact point. The contact point has a first contact and a second contact, and the first and second contact are mutually spaced in an open position and electrically contact each other in a closed position. The contact point is paired with an arc blow-out device in order to generate a blow-out field, and the blow-out field is produced such that an arc which is produced when the contact point is opened is blown away from the contact point. According to the invention, at least one of the two contacts has a non-conductive cover on the side which faces away from the contact and away from the respective other contact, said non-conductive cover preventing the root of the arc from crossing the side facing away from the contact.
