<p>The present invention generally finds application in the field of safety electric devices and relates to a reset device to be coupled to a limit switch (2), which comprises a modular housing (14), interface means (18) associated to said housing for removable coupling both to the head (4) and to the case (3) of the limit switch (2), reset means (13) at least partly accommodated in said housing (14) for controlled turning on and off of the limit switch (2). The reset means have such a shape as to interact with the actuator means of the switch to promote positive opening of the electric contacts substantially at the same time as the switch with which the device is associated is turned on/off.
