A circuit for suppressing the effect of rebounds of a contactor (2) on a control signal (C) produced thereby, wherein the contactor (2) ideally changes from one position to another position and remains in the other position for a predetermined time. The circuit comprises a sampling means (3) for sampling the control signal (C) at a first sampling rate (CLKA) and providing a output signal (Ci) being in either a first or a second state, a detecting means (4) for determining a change of said output signal (Ci) from one of said states to the other state, and a sampling prevention means (5) for preventing the sampling means (3) from sampling the control signal (C) for said predetermined time in response to the change in said output signal (Ci), in order that said output signal (Ci) remains in said other state for at least said predetermined time.
