Реферат: The magnetic switch, such as for cold starting of an internal combustion engine, has a circuit for its instantaneous attraction and delayed release. The switch excitation coil is incorporated in the main circuit of a transistor whose control circuit contains the main switching path of a second, complementary transistor. The latter base is coupled to a signal input via a resistor and a capacitor and it is also connected to the output electrode of the first transistor. The capacitor is coupled to a discharge circuit formed by the excitation coil of the magnetic switch and a diode which is poled in the blocking direction during the capacitor charging. The capacitor is in series with a temp-dependent resistor, bridged by the discharge circuit, and connected in the charge circuit.
