Control unit and actuator with control unit

An electronic control unit (1), comprising

• a housing (3) including first and second housing parts (20, 24),
• an activating terminal (5),
• a switch-off device (4), the switch-off device (4) comprises at least one reed switch (6, 18, 26) and at least one permanent magnet (7) arranged outside the housing (3) and removable from the housing (3), the at least one reed switch (6, 18, 26) is closed when the at least one permanent magnet (7) is arranged at the housing (3), and the at least one reed switch (6, 18, 26) is opened by removing the at least one permanent magnet (7) from the housing (3),
• wherein a supply link (8, 10) between the activating terminal (5) and at least one supply terminal (9, 11, 17) is established when the reed switch (6, 18, 26) is closed and is interrupted when the reed switch (6, 18, 26) is opened, so that voltage-carrying functional elements arranged in the control unit (1) are switched to be currentless by the removing of the at least one permanent magnet (7), and
• the at least one permanent magnet (7) is at least one of formed or arranged in or on a mounting element (22), and said mounting element (22) attaches the first housing part (20) to the second housing part (24).
