Abstract
The invention discloses an isolation switch. The isolation switch comprises a pedestal, a first insulation support and a second insulation support, wherein the first insulation support and the second insulation support are parallelly fixed on the pedestal. A first wiring plate and a second wiring plate are respectively arranged on top ends of the first insulation support and the second insulation support. Opposite ends of the first and the second wiring plates are provided with symmetrical static contacts. Two sheets of electricity conducting blades are arranged on the first and the second wiring plates. Two ends of one electricity conducting blade are fixedly connected with two ends of the other electricity conducting blade via two connecting bolts. A locking sheet is arranged on the lower end of the first wiring plate. A locking device used for locking the electricity conducting sheets is arranged between the two electricity conducting sheets on the first wiring plate. A stop support is arranged on the second wiring plate. A first stop pin inserting hole group and a second stop pin inserting hole group, which are mutually parallel, are arranged corresponding to the two electricity conducting blades. According to the utility model, it can be effectively avoided that hinged points of the isolation switch are used as main electricity conducting loops, so dominance of the isolation switch is enhanced.
