    • To facilitate assembly and provide for high-level output from a deceleration sensor which provides, inherently, only very low level output, an evaluation circuit, such as an amplifier structure, is connected immediately adjacent the deceleration sensor on a common metal plate, interconnected thereby by bonding wires, the common plate having connecting pins (18) passing therethrough for connection to a standard plug-and-socket connector; the evaluation circuit and the deceleration sensor are enclosed within a common sealed housing, so that both the deceleration sensor (12, 12') as well as the evaluation circuit (16, 17) are sealed against ambient influences, preferably retained within a high-viscosity fluid, such as insulating oil. All elements can be located on one side of the housing, in which a standard T5 transistor housing is suitable; or the deceleration sensor may be located on the other side of the metal plate (10) from the evaluation circuit, in which case a plastic housing can be used, only the deceleration sensor being secured to the metal plate by a metal housing cap, sealed to the metal plate.

    • A three-stage Darlington transistor circuit having a power transistor (T.sub.3), a driver transistor (T.sub.2) and an initial transistor (T.sub.1) is provided. The collectors of these three transistors are connected with one another, while the emitter of the driver transistor (T.sub.2) is connected to the base of the power transistor (T.sub.3), and the emitter of the initial transistor (T.sub.1) is connected to the base of the driver transistor (T.sub.2). Connected to the base of the driver transistor (T.sub.2) is a series circuit comprising a first resistor (R.sub.1), which is connected directly to this base, and a Zener diode (ZD), the anode of the Zener diode being connected with the resistor (R.sub.1); and a second resistor (R.sub.2); the second resistor (R.sub.2) is connected in parallel to the emitter-base path of the driver transistor (T.sub.2). Upon the attainment of a predetermined voltage at the cathode of the Zener diode (ZD), the driver transistor (T.sub.2) and the power transistor (T.sub.3) are switched ON. The temperature dependency of this switch-on voltage can be adjusted by varying the resistance ratio of these two resistors (R.sub.1, R.sub.2).
