The invention relates to a toggle switch. The toggle switch comprises a bottom case, a main wiring position is arranged at one end of a lower side of the bottom case, and two secondary wiring positions are arranged at the other end; a rotating plate always communicating with the main wiring position is arranged in the bottom case; two secondary wiring boards always communicating with two secondarywiring positions are further arranged in the bottom case; an oscillating part capable of driving an oscillating plate to oscillate through the oscillation and capable of communicating with any secondary wiring board and performing the resetting is rotatably arranged in the bottom case; an upper case is arranged at an upper side of the bottom case; a locking hole capable of performing location change along the arc trajectory along the oscillation of the oscillating part is formed at one end of the oscillating part; one side of the upper shell is slidingly connected with a locking bolt capableof being inserted into the locking hole so as to prevent the oscillating plate from communicating with each of two secondary wiring boards; a sliding chute is formed at one side, corresponding to thelocking bolt and far away from the locking hole, of the upper case; and a sliding block capable of pushing the locking bolt to insert into the locking hole along the sliding is arranged in the slidingchute in a slippage manner. The toggle switch disclosed by the invention has the effects of preventing the mistouch and protecting a circuit.
