    摘要: An electrical device for switching an arc to a path parallel to a device to be protected. The electrical device includes double breaking contacts and an arc transfer electrode associated with the parallel path. The parallel path shunts the double breaking contacts and a device to be protected via the arc transfer electrode. The arc transfer electrode is placed in the vicinity of a fixed contact of the double breaking contacts.

    摘要: A switch device using a main switch coupled to a monostable auxiliary switch through a releasable coupling is disclosed. In this device, the auxiliary switch and the main switch are closed in succession by simultaneous movement of their respective contact-holders and are opened in the reverse order by virtue of the presence of the releasable coupling which is released during closing and engaged during opening.
