• the capacitor C3 serves in this example as a backup capacitor and is protected by means of the zener diode D1 1 against overvoltage.
• the zener diode D1 1 itself is protected against overcurrent by means of the resistor R15.
• the diode D10 ensures that the capacitor C3 is not drained excessively quickly when turning the voltage and serves as a rectifier diode.
• FIGS. 9 and 10 can also be combined. This means that the connection leading to the transistor T1 via the diode D9 can also be provided in the embodiment according to FIG. In this way, the transistor T1 is not only bypassed, but also actively switched through.
• the third circuit part 13 shown in FIGS. 9 and 10 is not the only way of avoiding thermal overloading of the transistor T1. It is also conceivable that the third subcircuit 13 bridges the first transistor T1 when an opening movement of the door 5 occurs in a time interval long or frequently.
• 1 1 shows an electronic circuit 1 i with a corresponding third subcircuit 13, which monitors the frequency or intensity of the movement of the door 5 in order to prevent (thermal) destruction of the transistor T1.
• This comprises a threshold value switch IC2, which is connected on the output side via the resistor R14 to the transistor T5. At the first (positive) input of the threshold switch IC2 is connected via a diode D12 connected series connection of two resistors R16 and R17.

• a movement of the door 5 leads to a charging of the capacitor C4 via the resistor R16. At the same time it is permanently discharged via the resistor R17. If the door 5 is moved frequently and / or intensively, the voltage at the first (positive) input of the threshold switch IC2 exceeds the voltage defined by the resistors R18 and R19 at the second (negative) input of the threshold switch IC2, thereby turning on the transistor T5.
• the capacitor C5 serves as a backup capacitor, so that the voltage at the second (negative) input is virtually constant.

• the third sub-circuit 13 both the first switch S1, T1 bridged and / or drives such that its resistance is reduced when an opening movement of the door 5 occurs in a time interval long or frequently, as well as when an overtemperature of the first switch S1, T1 is detected.
• a third subcircuit 13 monitoring the intensity / frequency of a door movement is independent of an ambient temperature of the rail vehicle 10 or of the door module 3. This means that a vandal protection also starts and the door module 3 protects against excessive mechanical stress when the temperature of the Transistor T1 is still far from a critical temperature because of very low outside temperatures. At very high ambient temperatures, on the other hand, a third subcircuit 13 monitoring the temperature of the transistor T1 is more likely to be activated, which then activates the vandal protection even after comparatively few actuations of the door 5. A combination of the two measures accordingly combines the advantages mentioned. For the purpose of optimum protection, an OR combination of the two switching criteria is preferably provided for this purpose.
• the switch S1 or the transistor T2 is driven intermittently or pulsating and the supply voltage of the electronic circuit 1 a..1 g is buffered, for example with a capacitor and / or an accumulator (not shown).
