The present invention relates to a multi-way synchronous switcher. The multi-way synchronous switcher comprises a contacting tongue unit and a cam, the contacting tongue unit comprises an upper contacting tongue unit, an intermediate contacting tongue unit and a lower contacting tongue unit which are mounted in sequence; the lower end of the cam has a shape of step provided with several step stages; the first slider being able to move up and down is provided between the cam and the intermediate contacting tongue unit; the lower end of the first slider is connected to an elastic mechanism which can actuate the intermediate contacting tongue unit to move up and down. The multi-way synchronous switcher of the invention can perform multi-way synchronous switching; the knob can be turned in an indicated direction when the switcher is connected in a circuit; the contacting tongues can bear relatively large current, so that it can be damage-proof and has high reliability, small volume, simple structure and low manufacturing cost.
