Abstract
The invention relates to a device (2) for detecting manipulation on an object comprising an actuating switch (22) which has a snap-action disk (220) which can be switched between a first position and a second position, and an actuating element (21) which has a body (210) and an actuating stud (211), projecting from the body of the actuating element (21), for acting on the snap-action disk (220), wherein the actuating stud (211) has a first stiffness. According to the invention a contact element (213), arranged on the actuating stud (211), acts on the snap-action disk (220), wherein the contact element (213) has a second stiffness which is greater than the first stiffness.
