Zusammenfassung:	A ratchet tool with stacked switching device includes a handle, two stacked engaging assemblies, two springs, a toothed wheel, and a control unit. Each of the engaging assemblies includes stacked first and second engaging members. The engaging portions of the first and second engaging members are staggered. Since the toothed wheel selectively engages with the engaging portions of the first and second engaging members, the number of teeth of the toothed wheel to be engaged with the two engaging assemblies is the sum of the number of teeth of the engaging portions of the first and second engaging members, thus enhancing the fineness of the rotation of the toothed wheel, and improving the easiness and applicability of the ratchet tool, without impacting the structural strength.
