The invention relates to a long-stroke microswitch. The long-stroke microswitch comprises an outer shell, a first terminal set, a second terminal set, a button transmission mechanism, an elastic sheet transmission mechanism connected with the button transmission mechanism and the like, the first terminal set, the second terminal set, the button transmission mechanism, the elastic sheet transmission mechanism and the like are arranged in the outer shell, the button transmission mechanism comprises a first button and a first spring limited between the bottom of the first button and the outer shell, a transverse pressing portion is arranged on the side wall, in the outer shell, of the first button, and the pressing portion is located above the elastic sheet transmission mechanism. The button is pressed, the first spring is deformed, the button transmission mechanism transmits the pressing motion to the elastic sheet transmission mechanism through the pressing portion, then the terminal connecting relation in the second terminal set is changed, the terminal connecting relation in the first terminal set is changed, and finally electrical connection control over an external circuit is achieved. According to the microswitch, dual pressing transmission processing is adopted, the stroke capable of being set is long, the pressing hand feeling is increased, damage caused by improper operations to the microswitch is buffered, resetting is reliable, and the overall cost of the microswitch is low.
