| 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. |

1. An electronic control unit (1), comprising
a housing (3), 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). |
