The embodiment of the utility model provides a dielectric switch and a residual-current circuit breaker, and relates to the technical field of electrical components. The dielectric switch is used for testing the insulation performance of a residual-current circuit breaker, and comprises a fixed assembly and a movable assembly. The fixing assembly is fixedly connected to a preset position, the fixing assembly comprises a static contact group, the static contact group comprises a first static contact and a second static contact which are arranged at an interval, the first static contact is connected to the circuit board, and the second static contact is connected to the corresponding main loop. The movable assembly is movably connected with the fixed assembly, and the movable assembly comprises a movable contact group. The static contact groups and the moving contact groups can be switched between an on-state and an off-state, and the moving contact groups and the static contact groups have the same number and
