Engagement relay (20) for an electric machine, with the engagement relay (20) comprising a contact device (65) for the electrical connection of electrical contacts (120, 121), with a switching axis (67) which must be actuated for the electrical connection, with a thrust motor (60), which serves to displace the switching axis (67) and with the thrust motor (60) comprising a movable part (57), which serves to actuate the switching axis (67), the movable part (57) being connected with a driver (85), wherein a stop part (84) is movable relative to the movable part (57) of the thrust motor (60) and has a gap (s) between the stop part (84) and the driver (85) when the engagement relay (20) is in a state of rest,
- wherein a pin part (98) of the stop part (84) engages in a slot (95) of the driver (85), wherein the slot (95) extends between two end faces (93, 96) of the slot (95), and thereby guiding the stop part (84) and the driver (85) relative to each other.
