4. Operation overview
The switching amplifier provides the energy to switch points with
double solenoids. Applications:
Switching stiff points. It is possible to switch stiff points independent
of the power of the transformer.
Simultaneously switching several points. Each of them has to be
connected to a switching amplifier of its own and then all points can
be switched simultaneously via one impulse.
The switching amplifier works, drastically simplified, like a flash gun.
The electric charge which is necessary to switch points is stored in an
electrolytic capacitor.
The switching operation is activated via a transistor, by connecting one
of the inputs shortly with earth. To make the earth contact, a push
button, a control panel, a circuit track or similar can be used. Turnout
decoders are not suitable to activate the switching operation.
