    • In a sensor (11) for automatically triggering safety devices in motor vehicles, a toggle body (15) that acts as a seismic mass and that bears at one end a permanent magnet (17) is arranged inside the housing. The permanent magnet (17) is operationally connected to a Hall-effect switch (22). The toggle body (15) rests on protuberances (30) shaped in the bottom (14a) of the housing (10). The adhesion between the bottom (14) and the lower side of the toggle body (15) caused by humidity entering the housing can thus be maintained at the lowest possible level. In order to remove dirt particles from the toggling area of the toggle body (15), channels (36) that allow the dirt particles to migrate into a funnel (34) shaped in the bottom (14a) are formed in the conical area (13) of the housing recess.
    • 在用于自动触发机动车辆中的安全装置的传感器(11)中,用作震动质量块的摇臂元件(15)放置在壳体内并且在一端具有永磁体(17)。 。 该永磁体(17)与霍尔效应开关(22)有效连接。 壳体(10)的底部(14a)具有突起(30),摆动元件(15)搁置在突起(30)上。 以这种方式,可以尽可能保持底部(14)和摇臂元件(15)的下侧之间由水分渗透产生的粘附效应。 为了从摇摆元件(15)的倾斜区域移除杂质颗粒,在壳体的空心的圆锥形部分(13)中形成通道(36),其允许颗粒 形成在底部(14a)中的漏斗(34)中的杂质。

    • The aim of the invention is to conduct away the heat produced by the operation of a power component (10) soldered on to a circuit board (13) via a soldering surface (12). To remove the heat, through-contacts (18) are provided which are situated outside the soldering surface (12) and are electrically insulated by a length of insulation (19). These through-contacts (18) ensure good thermal contact through the floor (23) of the circuit board (13) to the heat sink (35). The length of insulation (19) ensures that the contact surface of the power component (10), which is raised to an electrical potential, is separated electrically from the contact surface of the heat sink (35), which is normally earthed. The intermediate layers (21, 22) which will also be present in a multilayer circuit board (13) of conventional design and the use of through-contacts (18) filled with tin further enhance the conduction of heat from the power component (10) to the heat sink (35).
