A wireless router that can be switched to operate at different wireless modes by repeated presses on a button includes a rotatable disk and a first printed circuit board. A first magnetic component and a first conductive sheet array are fixed on the rotatable disk. The first conductive sheet array includes first conductive sheets. A first and a second magnetic component arrays are fixed on the first printed circuit board. The first magnetic component array includes second magnetic components. The second conductive sheet array includes second conductive sheets. The wireless router is configured to be switched between wireless modes by rotating the rotatable disk to one of the wireless modes, the first magnetic component absorbs the second magnetic component corresponding to the first magnetic component, an electrical contact is made between one of the first conductive sheets and the second conductive sheet that is corresponding to the first conductive sheet.
