Abstract

The invention relates to a power switch, which comprises a plurality of contact pairs, and each contact pair comprises a first contact and a second contact which are correspondingly arranged and can be in conductive contact with each other or disconnected from each other; and the plurality of arc isolating covers are arranged corresponding to the plurality of contact pairs, and each arc isolating cover is provided with an isolating groove which is arranged on the outer side of the first contact and the outer side of the second contact. According to the power switch, the arc isolating cover is arranged, the arc extinguishing effect can be achieved at the moment when the contact is closed and opened, and therefore the risk that the contact is burnt out is avoided.

Description

technical field [0001] The invention relates to a power switch. Background technique [0002] The contacts of the existing power switch are prone to arc when they are closed or opened, and the contacts are easily burned out. Contents of the invention [0003] Therefore, the object of the present invention is to provide a power switch capable of extinguishing arcs, so as to effectively avoid the risk of contacts being burned out. [0004] In order to achieve the above object, the present invention provides a power switch, which is characterized in that it includes: a plurality of contact pairs, and each contact pair includes a first contact and a second contact that are correspondingly arranged and can be electrically contacted or disconnected from each other. Two contacts; a plurality of arc shields, set corresponding to the plurality of contact pairs, each of the arc shields has an isolation slot disposed on the outside of the first contact and the second contact.
