| 摘要 | An electronic control unit (1) or an electric actuator (2), respectively, have a switch-off device (4) which includes at least one reed switch (6, 18, 26) and at least one permanent magnet arranged outside the housing (3) and removable from the housing (3). If the permanent magnet (7) is removed from its position of usage at the housing (3), for example in order to perform maintenance of the electronic control unit (1) or of the actuator (2), respectively, the at least one reed switch (6, 18, 26) is opened, as result of which the supply link (8, 10) between the activating terminal (5) and the supply terminals (9, 11) of the control unit are interrupted in order to switch voltage-carrying functional elements of the control unit (1) and/or of the electric actuator (2) to be currentless and thus to effectively prevent an unwanted spark discharge. | ||||||
