Disclosed in the present invention is an isolating switch, comprising a static contact, a front conductive arm and an arc ignition device; the arc ignition device comprises an arc ignition plate, an arc ignition rod, an arc ignition frame and an elastic member; the arc ignition plate is installed on the static contact; the arc ignition frame is installed on the front conductive arm; the arc ignition rod is slidably disposed in the arc ignition frame; the elastic member is disposed on the arc ignition rod and can make the arc ignition rod move toward the arc ignition plate. Since the isolating switch in an embodiment of the present invention uses an arc ignition device, using an elastic member to drive an arc ignition rod into contact with an arc ignition plate, burning due to arcing will not occur between the static contact and contact fingers during the opening and closing operations, so safe operation of the electrical system can be guaranteed. |
