The invention provides a multipath plug-type contact change-over switch, and the change-over switch comprises an upper cover, a housing, a normally-closed contact device, a normally-opened contact device, a moving contact device, a conversion device, and a wiring device. The upper cover covers the housing, and the normally-closed contact device and the normally-opened contact device are respectively fixed in the upper cover and the housing. The moving contact device is disposed between the normally-closed contact device and the normally-opened contact device, and is connected with the conversion device. The normally-closed contact device and the normally-opened contact device are provided with pins, and the moving contact device is provided with jacks. According to the technical scheme of the invention, a mode of cooperation of the pins with the jacks is employed for the electrical connection of a moving contact with a normally-opened contact and the electrical connection of the moving contact with a normally-closed contact, thereby enabling the switching operation of the change-over switch to be more smooth, enabling the electrical connection to be more reliable, and enabling the switching operation of a plurality of groups contacts to remain consistent and synchronous. The change-over switch is resistant to high temperature, corrosion, impact and vibration, and is suitable for long-time stable and reliable use in a severe environment.
