Abstract

The invention discloses a rocker-type single-wire double-connection double-insurance switch. The switch comprises a shell, a rocker component, an electromagnetic mechanism, wiring terminals, a toggle board, a conducting strip and moving springs, wherein when a moving iron core is connected with the toggle board under the action of electromagnetic force, the toggle board is swung leftwards to rightwards along the action of a rocker; a moving contact on the toggle board is contacted with a fixed contact on a wiring terminal on the left side or the right side of the moving contact so as to form a turn-on circuit; and when the moving iron core is separated from the toggle board, the toggle board is only stressed by the elastic force of the moving springs on the two sides of the toggle board so that the toggle board is balanced between the wiring terminals to cut off the circuit. In the switch, the moving springs and the moving iron core act on the toggle board together so that the toggle board is contacted or disconnected with fixed contacts on the two sides to form an on or off state of the circuit. The switch can be suitable for the overheating protection, the overcurrent protection and the short-circuit protection of electric appliances, and has the advantages of reasonable structure, high safety performance and the like.
